Hope you don't mind me digging up an old thread... I'm really intrigued now by what you said, as the night before last I had a really disturbing nightmare that involved some kind of acid trip, even though I have never taken LSD before.
I am in a restaurant with the cast of Happy Endings, when one of the girls (not sure her name, Jack Bauer's daughter) wants me to go to the bathroom with her. She heads in one of the stalls and asks me to hold her umbrella. I take hold, and it grips me back, the metal arms wrapping themselves around my wrist.
Then a recorded voice comes out of the umbrella: "toxic gas release in 5... 4... 3..." and as I panic and try to rip it from my arm, a green gas pours out. I hold my breath. The voice goes on "this is nerve gas, the next release will be xxxxxx gas (I cant remember the word) in 5...4...3..." I'm freaking out, still holding my breath trying to get away from the gas as it releases different toxic fumes into my face.
Finally, I cant hold my breath any longer. I draw in a massive lungful of the gas which happens to be a highly hallucinogenic compound, the recorded voice says. Some guy rips off the umbrella and flings it out a door but it is too late. The dream explodes into nightmarish scenes.
One by one, different characters walk past with horrific things to say/show me. Kim Bauer says "there's blood everywhere!" and blood graphically starts pouring out of her joints. Then the others parade past, one is holding a baby about to do something horrific to it. Another is turning inside out from his mouth. Another is glitching in front of me with elements of The Ring coming out. It's not just gross, it's downright terrifying, I have a feeling of complete and utter dread in my bones. There is also a feeling of being trapped in space, like I can't escape mentally or physically, and this being inexplicably trapped plus all the mayhem makes me feel like I'm stuck having a bad acid trip.
I'm rocking in a corner now, and finally have the clarity of thought to shout "I'm dreaming, wake up, wake up!" Usually I would attempt to figure the dream out and have some lucid time too but this is all too overwhelming, I just want out. As I become aware of my real body in bed, something is just barely touching my right armpit, but in the dream this translates to that awful feeling you get when someone is tickling you hard and wont stop, it becomes more and more frustrating as the thing pushes into my armpit which I cant move or defend, until I want to scream.
The drama goes on around me, the dream scene flashing and glitching and weird creatures climbing the walls - and I can see it all even though I have my eyes closed. I shout "WAKE UP, WAKE UP" a few more times and finally GASP and awaken, as the unmistakable feeling of sleep paralysis wears off.
Even though I have never wanted to take acid in real life anyway, this nightmare has absolutely 100% put me off!
What inspired such a horrific nightmare? All I can say is, that night was the first night in a LONG TIME I actually got to sleep properly without having to do baby duty - 11 whole hours meant catching up on an awful lot of serious sleep deprivation. This, as I have learnt (along with all the other firsts this year), has given me some really shocking sleep paralysis / nightmares. I was also practicing WILDs around 5am (the dream happened at 9am) and I have a lot of real life anxiety going on right now. So, I guess I am really asking for it!!
