I used to have a friend that would see demons and shit while high, but he was so fucking burnt from dropping acid and doing other stuff. One time we were hanging out in my kitchen and he just started laughing, given he was sober at the time I asked him what the fuck he was laughing at. He told me that he saw a blue smirff looking thing run across the floor! I guess seeing cartoon characters isn't so bad compared to ghost and demons. I would suggest you don't hit as much next time. I believe that in the smoking culture people feel that you have to be macho and hit 5 bowls in a row until you lose all grip of reality, but i have learned that you neeed to respect mary jane and be cautious. She can creep up on ya and bite you in the ass if you aren't careful.
