hi all. i had this feeling the other week that someone was in the living room with me, my wife & son were in bed, so i was alone. i lay on the sofa and fell asleep. then this "person" appeared and put their arm accross my chest, not putting pressure on my chest or hurting in any way, but i could not speak, i was dreaming i was trying to shout out loud but no words came from my mouth. i then woke up feeling really cold and scared, although this "person" did not hurt me in any way. can any one explain??? thanks brian
