All of my "typical" dreams usually involve me getting hit hard in the head and panicing, it's pretty rough.

I've become more aware of my concious surroundings while dreaming as well, like I can sense when something or someone is going to interrupt my sleeping, it's weird and almost a "out of body" feeling. It has allowed me to avoid getting hurt or hurting myself while sleeping.

When I set my alarm clock, I'll always make up a few minutes before it goes off. There's also a train that goes by my house that'll likely vibrate my room, and I'll sometimes wake up a minute before it goes by.

Usually when I have a typically dreamless sleep and something wakes me up, I'll have a split second dream or thought right beforehand. Usually these "snapshots" are odd color or number excersizes. Such as one where I my brain was identifying different fruit colors in a tree or my brain was counting numbers.

Weird stuff, dreams are.
