Why do i feel like i'm kind of awake when i'm dreaming- i can't tell if they're dreams or not?

You could be both: You may be having hypnogogic phenomena. That is starting to wake up while still dreaming or starting to dream before you're fully asleep. It's not dangerous & usually transient. Perhaps there's been a recent change in your sleep pattern. Just sticking to basics, like no coffee or nicotine in the late evening should help.

Dissociation: It is possible that you might be in a dissociative state, which can be experienced as both awake and dream like feeling. For example dissociative amnesia, dissociative fuge or dissociative identity disorder.
