I can remember my dreams if I make the effort, but I don't unless it was really good, like flying or something.

if I make an attempt to do so first thing after awaking.

if it's a really powerful dream I don't need to do so right after awakening, but otherwise same here kuanyin

I only remember the really weird ones

I remember them when I wake up. Unless they're really interesting, I seldom remember them beyond that.
