Ask HN: What's happening to me at night?
It started a few months ago. You know those dreams where you are falling down.. and just before you hit the ground you jerk and wakeup, or sit up really fast? Well it started happening to me at night.. but multiple times. In the morning I don't remember the dreams.. or if I even had one. All I know is that at some point in the night I jerked or sat up awake.

Then it got worse.. I would wake up.. and my bed would be shifted. My pillows on the ground. and sometimes the bed frame itself shifted.

Then it seemed to calm down.. but not for long.

One day I strangely wake up.. don't know why but I woke up and sat on the side of my bed. The light was one.. I don't remember turning it on. I take the blanket with my hand it take it off of my legs.. that's when I notice the blanket had blood on it where I touched it.. I looked at my hand and noticed that there was a slice of skin missing from the tip of my thumb to the meet. That's when the pain hit me.

I put my legs on the ground and felt wetness. I looked down to find a cup I had on my air purifier had fallen over broken and spilled. The air purifier was also on the ground. I stumbled to my computer desk and noticed that it along with my keyboard was also wet.. another cup, full of tea had spilled all over my desk. My 2 monitors which were on the desk were also fallen over. The monitor on my computer on the floor had fallen over as well.

I walked to the bathroom to soak my thumb and noticed it hurt to walk. I looked down to find my foot bruised and cut one one place.

The creepy part is.. I don't know what the heck had gone down that night.

Fast forward a month. Everything seems fine. Until today.

I woke up.. bed was moved/sheets were moved. I went into the shower and started washing my hair.. then I noticed that it hurt to rub my hair. I looked at my hand and noticed that in the middle inside of every finger there was a cut and a bit swollen. Like I had gripped something extremely hard. And there was skin missing and a bruise on my foot. That's when I remembered something from last night.

My dad wakes up at 5 to go to work and he came into my room to see what was going on. I remember him walking in and me being on my knees at my bed pushing the bed. I remember me saying something about pushing it back because it had moved.. but i don't remember how I had gotten there on my knees in the first place. It was like my dad arriving had given me some conciseness of what I was doing.

In the morning.. my dad informed me that he had gone into my room because he heard me screaming "Don't touch me!" and found me on the floor. Creepy, I know. but i don't remember any dreams or saying that.

When he told my mom... she said that about a month ago she had gone into my room at night because she heard me talking.. it sounded to her like I was trying to argue a point.. but couldn't understand what I was saying.

I'm hear to ask if anyone has any idea what could be going on with me.

My mother had an idea.. she thinks it may be the unhealthy amount of coffee I have begun digesting.. day .. and night... causing some sort of brain chemical imbalance. This made sense to me because I started drinking more coffee about when this all started. So what I'm going to try is to reduce the amount of coffee I drink a day and not drink any at night and see what happens.

Any other ideas?
