OK, last night I was dreaming about some thieves who were trying to rob me (this isn't whole dream, just snippet that matters for the question). They were super ugly and mean. They tried to take my wallet, so I punched one with my leg right in the face. But, for some reason, my leg also moved IRL and I kicked wall with my foot. The pain was excruciating. Why did sleep paralysis ended before the dream did? Does this happens to anyone else?
