I've heard weed keeps you from remembering dreams, but start a dream journal and write EVERYTHING you remember from dreams. all of it. You can resume smoking bud if you want, in a few months, after dream recall has improved. I'm 14, but i've studied dreams and the unconscious mind quite a lot, and i smoke weed regularly. I remember a few dreams a week though, and they are almost ALL lucid. Just wait until you remember at least 3 dreams a week xD, and remember it probably wasn't just one thing. you can have a cup of joe or take a bong rip whenever, but your first step is a dream journal. keep me updated on your progress, and good luck!
