*sigh*I keep on having horrible nightmares about losing the ones i love....?

Just woke up from a bad dream......i keep on having these horrible nightmares. But this week they seemed to get a bit worse..on Tuesday i had a dream that my little baby sister kept on getting her hair cought to something and she was screaming in pain. And i didnt do anything about it...which kinda really pisses me off because in real life i would of helped my little baby sister :(. On Wednesday i had a dream that my sick and ill grandma finally died..that made me cry for a while when i woke up. Today...i had a dream that my family got murderd except for me..i just ran off and tried to escape...if that was real i would of died with my immediate family i cant imagine living without them. Do any of you guys have a clue what the heck is happening?...geez this is really eating me up. It takes me a good 10 minutes to realize that those were just dreams,but when im in them..they feel real. Thank you for whoever read it this far..thank you a lot. This is been going on for a couple of months now..but usualy the bad dreams are about ME getting hurt..now this week it was about my family...
