I noticed if I go to bed and sleep for a straight 5+ hours I will have trouble recalling my dreams.

but

then i also noticed if I take an hour nap 3-4 ( I haven't tried any other length of time tho) hours before going to bed I'll have a much easier time recalling dreams. Maybe it's just me.

When I tried to go to bed early I wouldn't be able to stay asleep and I would wake up after the first hour/hour and a half and wouldn't go back to bed until 3-4 hours later and that's when I realized I could recall 4-5 dreams from a TOTAL of 6ish hours of sleep (last 2 hours lost due to having classes). The B6 didn't seem to help either and that's when I fell asleep at first for 5+ hours.

I figured maybe someone is having trouble with recall and maybe this could help
