All right so I haven't been sleeping well... Well this morning around 7 I finally fell asleep, I went right into a dream that felt so real, at first I was walking along a long corridor, it wasn't very dark at all, a bit dreary but not dark, all of a sudden I felt someone run up to me. He was dressed in black, I think he was a guy. Well right when he stabbed me in my heart I woke up just right before.. I jumped out of my bed and nearly fell over from dizziness. Can someone please tell me what my dream means.
