A dream forgotten

Sometimes I wake up with so many little dreams that I almost remember. Sometimes I dream that I wake up and am about to get out of bed when my boyfriend wakes up also and I tell him what I dreamed and so am able to safely forget it and then I wake up again, this time, I assume, for real, and I remember the last time I woke up and that it obviously must have been a dream, and I remember telling my boyfriend about my more interesting dream that I now cannot remember and so cannot write down in my notebook to remember for all time. I feel rather rested, so it's not a night's sleep wasted, but all those dreams I have spent the last eight hours going through 90 minute sleep cycles to get through no longer seem to be stored in an accessible area of my brain. What a fucking waste.
