Late on the dream topic.
I don't have nightmares, almost never have. I don't dream all that often anymore. My most interesting dream is this one though.
I "wake up" and see there are two hooded figures, their robes are all white (no not the KKK type of robes) and there was a white tiger sitting next to them. I woke up a moment later sitting the same why I was in the dream.
After that though I do get these deja vu moments that are snippets of the future, unfortunately I don't know about them until that moment actually comes.
