Can Anyone Explain This? Options

I'm pretty sure I know the answer to this, but I wanted to open it up to other interpretations.

Two nights ago I was sleeping at my girlfriend's place. I had a pretty restless sleep (felt like I was awake all night).
Just before I drifted off after waking up for the tenth time I distinctly heard someone shout the word "out". Now what was strange about this was that I didn't hear it with my ears, I heard it in my head as If I was thinking to myself, but it was a different voice to my own.

The voice was a man's voice of about middle to late twenties maybe earlier thirties and was very clear and powerful sounding (demanding me to get out?) however, I didn't sense any sort of anger from the voice, it sounded powerful and demanding as I just mentioned, but I didn't fear it. Of course I got a bit of a shock hearing someone else's voice in my head.

So at first I thought my studies are getting to me and I'm going insane but I then though about my training in CM.
The last few days I have done the LBRP every day. Before this week I found it hard to find the time to do a ritual at least once a week. So I thought that the increase in magical practice has increased my awareness to the spiritual environment and I have telepathically picked up on some spirit's vibe who has apparently been telling me to get out from some place (girlfriend's house?) and I have only started to tune into it.

It didn't happen last night at my place so I'm guessing the spirit is based at her place or just visited me.
I don't know of anyone passing away at my girlfriend's house (her family has lived there for about 12 years) and nothing strange has ever happened to her place which could suggest a haunting, so I'm baffled as to why I heard this voice.

Of course I could just be going insane (IMG:style_emoticons/default/insane.gif)

I decided to post this to share my story and to get some opinions. So what do you guys think?

Thanks for the feedback guys.

You might be onto something. A guy she knew (he had a girlfriend) and was our age hung himself probably about a month or two ago. I remember on several occasions that my girlfriend heard from her friends who knew him that he thought she looked alright. Maybe it's him? He did have a girlfriend though so I don't know.

I'm almost certain it wasn't my voice. The more I think about the voice the details get foggy so the whole age thing could be off completely. When I yell In a commanding situation my voice gets a bit lower and I feel my vocal chords struggling. This voice was more like a deep, sharp "out" and reminded me of a fat, bald guy standing up and shaking his fist in the middle of a board meeting (IMG:style_emoticons/default/13.gif) . The voice sounded like it came from the diaphragm not like what I would do. My yells/shouts come from my upper chest throat area.

The more I think about it though what your saying could be the truth. It could have been my voice. Is it possible that it could be disguised?
