How often do you dream?

I used to have some kind of pattern where I would dream every few days, but as I grew (somewhat) older this changed. If I get lucky there’s only one or two a week in it for me.

With ’‘dreaming’’ I mean that you can still remember (parts of) your dream, because if that’s left aside you dream almost every night (and only remember it when you wake up in your REM-sleep). I think we should count nightmares as dreams too for this one :)
