Weed is the most amazing thing to effect mental imagery, I used to take long walks through my mind while taking the drug but in the long term it doesnt help....

esp when you get to that stage when you feel like your having an OBE and your heart is beating fast (scary experience).

I know it sounds 'gay' but try and stay off weed for a few weeks, see how it effects your dreaming........

Its like you have opened the door but you dont need to keep walking through it (if that makes any sense).
