Okay, i was watching Channels Tv some minutes ago before Power Holders decided to seize the electricity. The movie started with a female doctor working and later got into her car and while making a phone call had an accident.

Afterwards, a man looking for an apartment gets her place and moves into it and then she suddenly appears to him telling him to leave her house at once.
She fails to realize that she's dead and the guy begins to think he's crazy. Eventually, he had to help her find who she was and in their search, they arrived at the hospital where her body lies in a comma. But only this guy could see her.

Now i'd like to know the name of this movie. Thanks
