Most of my dreams these days are filled with running. I'm chasing after something or, more often than not, running from something. I never see what I'm chasing, or what's chasing me. I never catch it, or get caught. There's just the running and the chasing.
In the dreams where I'm running from something, there's always a problem with one of my legs. It's injured or, strangely, it seems like one leg is dramatically shorter than the other.
Sometimes it jars me into that kind of conscious dreaming state. Part of me is aware of dreaming, but I'm just a spectator in the dream. All I can do is watch and feel myself try to run with that distorted gait.
My dreams have been like this for a few years. I wake up worn out and with tired legs, as if I had been running.
