It was about a group of friends the one scene was this guy and his girfriend in his bed. Then their friends start coming in his there all going on this camping trip like be for they start college. The main guy in the movie has these dreams about when he was younger the house he was in was on fire. The other thing I kn is either its an ex girlfriend of his or she just likes him but she kills there friends off one bye one. I need to find out what's the name of this movie is.

I suppose it's because of the burning house and the killings that make me think of this very obscure film. I probably am way off-base, but I'll give it a try.

IMDb synopsis:
Sam Reide has the ability of traveling to the past and works with the police department solving unresolved crimes, witnessing the events with the support of his sister, Jenna, and reporting the criminal's identity to Det. Dan Glenn. When Elizabeth Brown~the sister of his former girlfriend, Rebecca, who was murdered a couple of years ago~pays a visit to him, she tells him that she has just found Rebecca's journal with evidence that Lonnie Flennons, who was accused of the murder, is innocent. Sam decides to witness the murder of Rebecca, and his interference affects his present. He travels to the past to try to fix his mistakes, but every time he returns, his present is in worse condition.

IMDb review excerpt:
A man is able to travel back in time by getting into a bathtub full of ice and turning off the lights. He's got a mentor for this, who tells him to just watch what happens in the past and never intervene, lest there be ugly unintended consequences. His sister is always with him, checking his vitals and so on while he's "away". We learn that one time he did intervene, when, as a teenager, his house caught fire and he went back in time to save his sister; as a result, his parents died. // This fire is a recurring moment in the story, or so I seem to recall.

EDIT: I really feel as if I missed the mark. I don't think there are friends getting together. I guess later, I can delete most of the material when this gets a "FAIL". *smile*
