Was I lucid and can't remember?

well I went to the cinema to see inception last night and it seemed to take a starring role in my dreams.

I don't remember a great deal of detail the dreams of last night. I was watching the fight in the hall of the hotel when the gravity has shifted and then something changed. I can only describe it as that all of a sudden everything changed from a dreamlike quality to being real. It's hard to explain, for about 60 seconds or so it became real in me head, my awareness had changed or something but the most frustrating thing is I don't remember anything else.

Does that 1 minute window mean I was lucid but just don't remember, or just a really weird quality I've never before had in my dreams?

If you were aware you were asleep, then yes! Otherwise the dream just increased in vividness, for whatever reason.

I knew I was dreaming I think. The only thing I can really remember is that feeling though, after the awareness shift I remember nothing else but the feeling. It's so annoying if this was my first lucid and I don't remember it!
