I Wonder

I really wonder why some nights people remember their dreams, and other nights it's as if you didn't dream at all.

Almost every night this week, I've woke up remembering my dreams clearly.

Are dreams a mere rehash of events from your day/life/conscious thoughts? Or is there more to it than that?

Do they stay glued into your memory because you are supposed to pull some sort of realization from them? Or did you just happen to wake up in a cycle of dreamland that allowed you to recall?

I wonder.
