The first one about Jackie, I have my suspicions about it.
First of all, there's really no way I know of where you can tell what a substance is with out taking a sample and taking it back to the lab... but perhaps, a forensic chemist or some other field of specialty could speculate by seeing this footage... but I am sure, that with out any doubt in my mind... if a Forensic scientist got a hold of this strange substance he will with out a doubt identify it. Secondly, you really see no visual or audio evidence to suggest what they claim to have experienced to be true... And last but not least the "mysterious rash" is hilarious to me... Why didn't she take her baby to a Doctor? i'm 100% sure any Doctor could examine that child and recognize what that rash is... I'm not a Doctor, but I know babies always get rashes....to me, it's nothing more than amateur acting.. Instead of calling scientists, she calls a photographer... I think it was all in her mind, and there were collective delusions being experienced. .. so to I believe the first story to be totally bogus.
Ok the second story, I admit..at first look, it strikes you.. but there is no way to really be sure if this footage is real... perhaps a video expert can tell, or give his opinion... but to me... simple physical mechanisms could of been happening here to move it all.. and the entity behind the puppet strings... was some one in the family... I don't think anything paranormal happened here... I mean, you watch Criss Angel.. he's shown us how he does the "Flying" thing... and it's really quite simple when you actually see how he does the trick... and he does it infront of people... so for somebody, to have all the time in the world to think of a way to make all these objects move...in the privacy of his own home... with an immobile camera.. is really easy... magnets could of been used.. somebody could of been hiding under the table... a rope could of been attached to the chair.... this is not my field, but i'm sure somebody could explain how it was possible for all these objects to be manipulated by a human.
As for the third piece of the chair moving in the middle of the room and the piece of wood flying across the room... I think that's a little too advanced for me to even attempt to explain... but once again, just because there is no evidence of foul play doesn't mean foul play isn't the culprit... we only have one piece of footage to look at... one angle of the room.... there's so much of the puzzle missing.. again, I think this is just all special effects.
The fourth one, what can I say.... I don't believe in evil spirits possessing you.. I think it's a mix of watching too much tv, with a psychological disorder, with a little bit of acting, with a little bit of boredom... and there you go... you have a story like this...I can easily create the same footage and say its the most compelling evidence of all. And now for the moving chair... c`mon... its legs are not in the camera's frame.. somebody could of been lying down on the floor and pulling the chair back... I believe these two "Demonologists" to be con artists... and nothing more... there is not enough evidence to make their case.. so for now, its all not real....and the table? same story, you can't really see what's behind the table.. so for all we know, it could of been somebody kneeled down... pushing it... or not even any human... maybe a mechanical mechanism that did this.. did all the strange "objects moving on their own" footage. How come is it, when ever the objects move... you don't see the whole object... you only see the part you'd like to see.. it's a nice illusion.. but it's not real... the Mother is the one who's actually making the chair move, you can almost tell when they focus the camera on the little girls feet and then show the Mother again. Same thing with the table, you can't see the other side of the table.. somebody could of been standing there.. ready to pull it back
As for the case after this one... the answer is so simple
"# the person wakes up, but can’t move. This experience can be accompanied by : the feeling of a presence in the room, hallucinations in the form of a threatening shape and the feeling that something heavy is going to sit on the body. We can all this a disturbance in coming out of a dream. While dreaming, the muscles are paralyzed by the brain to keep the dreamer safely in place. In the sleep-paralysis the person is conscious, but the paralyzing-mechanism has not yet been ‘switched off’. ..."
I believe what they say to be true, but it was really all in their mind... and not paranormal.
Now to the music video shoot, that's not a figure of a mysterious man.. that's many other objects and surfaces combining together to give you that... you see, if you look in a microscope... at organelles (your cell's versions of organs) .. you can see so much, each of us can imagine something.. kind of like looking at the cloud... but in this case, they all collectively decided to view this object as a man...
The one about the object running across the hall, you'll need a physicist with an expertise in light to speculate on what it is.. but I don't think it's a dead arm.. rather than reflection of light... or some other explainable mechanism
Old mansion = fake images....
Then the series of people talking... well they're simply delusional and too bored.
And about hte little girl well...if they claim picture after picture same story... we should take the young girl to an objective room away from her parents.. in a completely empty room, with several different types of cameras the parents never touched...take the photos, and then see if this mysterious and strange... white ribbon like object appears... my bet is, they won't. And plus with her family's behavior, she's going to end up mentally damaged.. they're putting all these unreal ideas in her mind... they're feeding on to an infant's imagination... and making it harder for her to accept reality...
And all these white lights are probably just a photographic anomaly or doctoring of the footage... either way they're not ghosts.. and I find it hard to believe the testimony of a child when I recall as children.. some of us if not all, had imaginary friends and have imaginations as wide spread as wild fires.
Look, that psychic said he sensed there were gallows in the area.. great.. but if you die from a viral infection, or a gun shot wound or falling off a cliff or getting hit by a car... death is death.. I believe it's all in our own imagination and man made theories that... the only time ghosts "stay" back on earth is if they died a "horrible" and "untimely" death... well to me that's all baloney... it doesn't matter how you died, there's been an unimaginable number of organisms that have lived on Earth in the past 5 billion years... and I don't think a person that died from asphyxiation is really all that special enough to stay behind.
Look everything can be explained with enough evidence, and if a specialized scientist can not explain these videos its because there is lack of evidence ...
It's all in our heads... there are no ghosts... there are no demons... the only evil on this planet is being caused by us .. but I suppose it's always nice and comforting to blame evil on some unexplainable life form instead of taking the responsibility our selves... ghosts don't exist... this is all in our heads
