i had constant nightmares almost six days a week until i started smokeing regularly. I didn't notice that it stopped until after a couple of months ....i was thinking about a bad dream one night and i noticed that i hardly ever have had a n y recent nightmares....that is awsome.........going right to sleep after smoking alot i somethime go right into a dream and then i realize that i am really still awake and i jolt like when you fall in your sleep, it's like yyou really might have gone someplace else, i don't think that is true, but it feels like a major trance, it's scary at first, but when you rmemeber what the hell's just happened i have to laugh...
i have found that if i have some weed that is heavy toward the sativa side i will have wild dreams, more indica i am just knocked the hell out. lol
