Not sure if this is a repeated dream

I had a dream one night. And for the next 2 weeks everytime I wake up I think about it, did I really have that dream again, or am I just thinking about the original dream?

I don't think anyone but you can really answer that. But it's certainly possible that you've had the same dream more than once.

Have you written down this dream? If not, I recommend you do so. Then the next time you wake up thinking about it, you can review what you wrote down, and see if any details have changed.

I have a different but similar experience: I'll occasionally have a dream, and when I wake up it'll feel so much like I had it before, but as I become more aware I realize I never recorded a dream like that, and it's hard to believe at first that I didn't. I'll often even "remember" things that I've done in the previous occurrence of the dream that I didn't in this dream.

I can't rule out the possibility of actually having had the dream before and just forgotten it, but I have no way of verifying it. Also, I suppose that dreams can simply invent memories which can be confusing. So dreams like that are kind of weird. But this has happened quite often in the past, and so far I've never recorded duplicate dreams in my journal.

i have had dejavu in dreams. Maybe this is what you are experiencing.
