This 100% happens when im trying to fall asleep.

In the beginning it was "conversations" between 2 people, that i know or just hear their voice, the convos were usually random.

Next it became 1 person, also saying weird things like "Check the fridge" or "Get the ball"

Now it has become pretty scary...
First i heard was a weird "gargling" sound, as if someone is choking on water or blood... 
One time it was "We'll get you"
The last was "Just do it!" In a very angry and threatening voice.

I also hear sounds of cracking wood, ticking, and the ardacasional explosions (Exploding Head Syndrome)

Sleeping has become very very difficult, i get panic attacks before im just generally scared to hear these things.

Anybody know whats up?
