Okay so what you want to do is get your house blessed, it doesn't have to be a priest or a pastor just someone who really, truly, honestly, believes in God. Whatever you do, do not get angry or scared, spirits fees off of negative energy, they thrive off of it. Don't hold any seance's.

Seance's, if done wrong, can invite more evil spirits into your house. Also you need to think about the possibility that maybe it was your mind playing tricks on you. Late at night when you aren't fully awake your brain will screw with you.

It must have been the spiders.

Did you at least finish?

I now have something to prank my wife with. All I need is a motion sensor that sets of a short timer, then it hits play on a digital voice recorder hidden under the tank. How the hell am I still married?

Find a local paranormal group or talk to a pastor. If you feel it's paranormal. Otherwise eat healthy and exercise, and try to get sleep, hallucinations can happen out of the blue. I've had the same thing happen to me

Time to move.

There are over 80 different sleep disorders and most people are a ffected by at least a few. One of the more common ones causes auditory hallucinations while half asleep and the most common hallucination is someone calling your name. It's just your brain, nothing to worry about :)

Happened to me before too. I was brushing my teeth, and heard my name called from the mirror. I screamed, and forgot how to open the door.

Carry a loaded 12 gauge with you at all times, just to be safe XD
