Space between waking and sleeping

The Space

I am so scared when my mind is not anchored to reality, because in between that space between sleep and wake there's only terror. I cross that space everytime when im drifting into sleep, I start loosing the sense of reality, but then in my mind an image of a car swerving into me will jolt me awake. And it takes me a few seconds to realize it was just in my head. If I try to go back to sleep it will just happen again. I sort of have to break the momentum of unreality by getting up and going somewhere else in the house. I tell myself " My name is Rafael, its 3 o clock in the morning on a Wednesday night" If I stay in that place, all I feel is anxiety over the most random thoughts that don't make any sense.

Lately I've started to hear sounds in my sleep, that will wake me jolt instead of images. The people upstairs tend to make alot of noise and its really getting to me. when I'm trying to go to sleep I'll hear a thunderous bang from upstairs in my head and it will wake me back up. The first time it happened I thought I was going crazy, because if I went back to sleep I kept hearing the sounds and they would keep waking me up. I would stop hearing the sounds when I would sit up and try to keep myself from drifting into sleep. Its scary.

If there is a hell its this space/transition..it does strike the fear of god into me, what if this is what happens when you die, your consciousness is stuck in this zone foreever. This is the closest I could think of being in eternal flames.
