I read that people who take melatonin, one of the side effects is "very lucid/vivid dreams" - most people don't like this effect, but I find it very interesting!

Anyone have any stories?

Mine is that I had a harry potter dream once, and at the end of it I dreamed that I had a port key (teleportation device) and Gilderoy Lockhart sort of gave me one and I was transported (like harry was so many times) to Voldemort and lets just say it was a realization that I was dreaming, and felt "drained" and knew I'd wake up physically or mentally tired. If you've seen the harry potter movies, it was my experiencing all of the Voldemort encounters all at once in the 1st person!!!
I guess it's easier to remember dreams when they are "more alive". It also has 50% of Vitamin b6 in it. I also think maybe it activates a part of the brain that releases repressed memories that are released in dreams? Anyone else have any theories?
