Blood in my mouth..

I think that I shouldn't watch any crime stories or ghost stories anymore before sleep coz every single details will appeared again and again in my dream. For the last few days the same plot of dream emerged, my mouth was covered with blood, it was like I'm having some kind of diseases...I was choked with blood in my mouth..There were few people with me but they can't do much to help.It was so real until I woke and it feels like the blood is still in there..This act of waking up in the middle of the nite has make me tired...I had this dream 3 times since last week, maybe I was too tired driving everyday from Putrajaya to Subang Jaya, or maybe too much horror movie..It's just a mind game..But I must admit that I hate waking up in the middle of the nite in shocked!...Lemah semangat kot? Sometimes people says that a dream is like a signal or a warning, I don't know how true it is...orang cakap selalunya maksud mimpi tu terbalik..so kalau mimpi jumpa duit- meaning kita nak hilang duit..macam tu?..
