About 5 years ago I was using Chantix to try and quit smoking (if you don't know Chantix messes with your brain so its got crazy side-effects, including "weird and vivid dreams, suicidal thoughts etc")
Anyway the "weird dreams" were ABSOLUTELY happening, and they were all so vivid I'd honestly wake up every day feeling exhausted because I lived another life every night. Strange thing was they were always borderline nightmares (ie very disturbing and gruesome) but never felt like nightmares.
The best/worst one was probably the Miley Cyrus dream: Long story but ill throw down the highlight-reel:
-I was swimming in a giant lake with millions of floating dead bodies in the middle of the night and some strange underwater creatures lured me to the depths (i could breathe underwater no big deal).
-In the middle of the lake was an underwater labyrinth whose entrance encompassed heads-on-spikes and fire (the underwater kind of fire apparently)
-The creatures tell me - "make it if you can" and I enter the labyrinth, because - obvi why not?
-Proceed through said labyrinth systematically watching everyone I know/love being tortured (brutal)
-When I get to the middle, there is a Colosseum packed with more dilapidated sea monsters
-fight and kill the biggest/baddest sea monster
-crowd goes wild
*Announcer* "CONGRATULATIONS!!! YOUR PRIZE IS A DATE WITH MILEY CYRUS!!!!"
Me - "WHAT THE FU...."
*wake up*
Honestly, I often think it might be worth taking Chantix again just to experience some of those dreams again
