It was a movie made between 2006 and 2009. The story was based on a group of people breaking into an abandoned hospital and something ghostly or demon wise was chasing them threw it. Also I remember that when the looked out the windows of the place time outside had stopped. If anyone can let me know I would greatly appreciate it. I think the cover of the dvd had a figure with something to the effect of a crow head. Not 100% sure

Here are a couple of possibilities to start with:
