Maybe I don't dream much either. I'm a solid sleeper and don't really move around in bed.
I never have nightmares either.
I go through phases. I might not have a single dream for a month, then have a dream every night for 3 months after. I don't sleep as solid as I used too. I think stress is a big factor in that though.
