Strange dream, heavy feeling.

[Midniteshowers]

A few weeks ago, I got a temporary room mate, and the other morning, I had a very strange dream that I cannot seem to shake and was wondering if I could get some feedback on it? Okay, here it is...
I fell asleep on my couch early in the morning, but it was one of those sleeps that you can kinda hear what was going on around you. I sensed "Jim" in the room and suddenly had this feeling of pressure on my stumache, right below my rib cage. I thought for a second that he was shaking me to wake up, but the prressure got heavier and started to hurt. I could hear what was going on in the room, (The window was open) but had a hard time prying my eyes open. when I was finally able to open my eyes, he wasnt there, nobody was in the room, and the pressure, pain, and inability to breath immediatly went away. I told "Jim" about this, and he was puzzled, and said something about psychic vampire. I have no clue what happened, just know that I didnt like it and cant shake the feeling I had while dreaming.. Can somebody please give me some input? Thank you, Manda
