Really good lucid dreams can be so amazing that I can't sleep for 2 or 3 hours after waking up. It is as if I was really there, and just teleported back to my bed. Everything is recalled, although some specific details stick out clearly and other details not so much upon reflection. And you still have scene changes, and don't think "Wow that was weird". But you are THERE in the PRESENT and can think and decide, which really makes it totally different from dreams.
