Within this last year I have been having this phenomena where my old dreams, even dreams I've long forgotten in waking life, come back to me as a real life memory in a dream. Even though I would know in waking life that these were dreams and not real memories, in the dream it feels so real and I believe that it actually happened. For example I've had dreams where my wife and I had a new baby, then months later in another dream I remembered this and got a little panicked talking to the dream version of my wife because I was like "We have another kid, where is he? How did we lose him what happened?" Another example is this recurring airport where I have to fly somewhere across the world. I will remember these as if they really happened. Its as if I keep returning to the same universe and retain the dreams as memories inside that universe...its like some kind of alternate reality I go back to. Has anyone had any experience with this kind of thing or any insights about this? I feel like this could be an easy path to becoming lucid if I can remember to reality check during these moments but I just never do, they're always very long adventurous realistic dreams and I really love them still even though I'm not lucid.
