For as long as I remember, I've had dificulty getting to sleep. Not all the time, but a fair amount of nights across my life. When I was really young I remember lying there in my room, unable to sleep. While I lay there I watched this... I don't even know how to explain it... Flow of dust, I guess. It would start from either the door or the roof and there were what seemed like billions of particles moving through the darkness, all across my room. It's weird that I've forgotten about this, but has anyone heard of some sort of eye problem relating to this? What I saw couldn't have possibly been real dust (unless there were many secret machines in my room), so could it have possibly been water particles on the surface of my eyes? I know this description is vague, but it strikes me as odd that I haven't heard of this before. Whole rooms becoming channels for floating materials continuously moving through. No, I'm not drunk.
