Did you guys read any of those experiences? Jesus that stuff sounds fucked up...
That's the shit satanists use for their rituals, if that tells you anything.

EDIT: Read this:
" First of all I like to inform all that playing with belladonna is like playing with dynamite. LSD, X, DMT are no comparison to atropine based plants. With most these drugs no matter what you see (I do not call for example LSD a hallucinotory susbstance, it causes severe distortion of sight, sound and mind) you are still aware that the plant or chemical are responsible for the effects. With belladonna the entire concept of reality goes down the drain, the very fabric of reality will break down. you can be sitting down watching t.v. at one moment and next you see your dead grandmother next to you on the sofa asking for more tea. I am not kidding here you will not know what is real and what is not. I personally took a bath with over million insects and did not know that this was not real. You can be contacted by numerous alien entites (remember witches at sabbat using among many other things belladona, visiting satan himself) that either can frighten you to death or make you touch an angel. Now enough scaring you. No, not enough you can easily die and I mean easily. "
