I haven't been smoking weed for very long, and honestly I haven't enjoyed it as much as I used to, it's more of a way for me to repress and get away from things (not in a good way).  I may quit smoking all together after I finish what I have, I feel like it's been causing more harm than good.  I don't have psychedelic trips while smoking weed (from what I can tell), it's more of a a relaxing state and I just kind of zone out listening to music and watching the iTunes visualizer.

As for the dreams, I haven't remembered my dreams for a long time, except for every so often I'll have one that I can remember.  It kind of sucks because it just adds to my self loathing not being able to experience dreaming.  I'm going to try the AlphaBrain supplements from onnit.com, people have reported feeling better taking these and actually remember their dreams along with having lucid dreams.
