A night out

You just went out with your friends and had a great night. However, when you wake up you find yourself in a  mysterious mansion without any memory of how you got here. Something seems odd about this house. Some strange things are happening. It kind of seems to live!

Find the keys to all the rooms and areas in the house, find out the story about this bizarre house and just get out of there as fast as you can, before it is too late.
