I dream practically every night, a few times a night. Generally, I can remember my dreams for at least the first half of the morning, and if I try to write them down the memory will last longer. I don’t generally have nightmares, I haven’t since high-school. But sometimes a dream will leave a bad impression. It isn’t a nightmare, but it isn’t comfortable - like dreaming of a death, or dreaming of our ghosts. Those dreams seem to live a little longer in my mind, and I'm less likely to take long walks alone when I had them.
