I have usually two dreams a night that are fairly long and can remember, but time is hard to judge in a dream for me. if i guessed, each one took about a half hour. i have a very profound dream maybe once a month, and have noticed some wickedly vivid dreams after a night of drinking hard liquor. As for control over my entire experience in dream (IE lucid), i have had only five i consider worthy of such a name. each was amasing, involving superhuman feats such as teleportation, strengh, human flight, and speed. I also am into music alot, but never dream of music (very rare) although i heard musicians seem to be sensitive to dream states.
