I've always admired people that have vivid dreams, sometimes full length movies in living color. A friend of mine could even return to hers after waking up, go back to where she'd left off and continue the "movie."
My dreams are weird. I dream in disconnected snapshots and usually in grayscale. Most of the time, I do not remember my dreams. Rarely do I dream of people I know, rather, the people in my dreams are strangers. Sometimes, a stranger will "feel" like he/she is really a particular person I know, but with a stranger's face.
Supposedly, non-physical beings communicate with us in the dream state. I wish I knew what they were trying to tell me! I've tried giving myself suggestions before retiring to dream more clearly and to remember them in the morning... to no avail.
It would be interesting to know how other people dream... if you'd like to share.
