I keep having a dream that a spider is hanging above me and i actually wake up and see it and dont know if its?

i keep having a dream that a spider is hanging over me. not like a long elapsed dream or anything........but I am actually awaken by inner forces for some reason and as soon as i open my eyes i am met by a spider; sometimes big sometimes rabbit size. As soon as I try to kill it or something it disappears. Now this is actuality because it just happened now and I am typing this. I cant go back to sleep because I am terrified. I have never had a phobia for spiders. I don't know what it may signify. Please help a.s.a.p.!!!!!!!
