Dreaming, or was I?

I keep having this dream. Where I wake up -- I feel awake -- and I see someone standing over me, or in my bedroom. I can't really make out who the person is, they seem masculine, and I feel incredibly scared and try to scream, but as much as I open my mouth and strain my throat... I can't scream.

Dream moods feels the following about the dream:

To see an intruder in your dream, represents your feelings of guilt. Consider also what unfamiliar feelings or thoughts may be breaking into your peace of mind.

If you try to scream, but no sound comes out, then is suggests that you need to immediately confront some situation. Perhaps you are unable to pinpoint your fears or feelings.

The following night that I had this dream recently my brother cut through my room in our vacation condo to use the bathroom. I was awake, but confused about whether or not it was the dream again or not. He's just lucky I didn't have my golf clubs in the room! Feelings or not, I find it hard to shake the feeling the next day that it wasn't really and to believe that there wasn't a person in my room.
