Becoming "Unlocked" in dreams.
When I'm awake I find it hard to recall what kind of adventures or experiences I've had in the dream world, I can remember a hand full but that's about it. However, while in the dream and especially when becoming lucid it's like experiences that I've had and even forgotten about comes back. I remember things I've done, how to do thing, things I've been taught and adventures. Sometimes it can be things that happened months or even years ago.
Does this happen to you as well?
