This may seem like a really stupid obvious question but i must know. I used to use a number of drugs so I know that the same night you've taken whatever it may be. ie. shrooms you are likely to have a strange dream, or even marijuana. however these effects are not permanent. But, last week I tried acid for my first, hopefully last (i like to try everything once and get it all out of my system so never again), it was very potent stuff. i didn't sleep the night of the day i took it, and the next few days were a blur, plus i was drunk. however, now that I am all sobered up for the last 2 nights i have had the most disturbing dreams. I actually woke up screaming last night. in a cold sweat and when i went back to sleep the 2 times after that i had more graphic nightmares. is this usual? and will this eventually stop. I know acid can change a person's perception permanently in some ways. this is what worries me drastically. that my young angsty one time decisions will have life changing effects. sleepless nights are not cool
