This may sound strange but my happy place (and I actually called it my happy place) was towards the end of my yoga classes. After all the hard streatching and stuff we would lie flat on the floor and just lay there completely relaxed...loved that part of the evening.
I also LOVE my bed up at school, something about that egg crate and my pillows that make is soo nice...and when it rains, it's the best place on earth.
