I have been told there is a body diode inside however my simulation shows power travelling from drain to source and vice versa. I thought there was a body diode inside that would only allow for current in one direction.

A common way to draw a MOSFET is by using this or similar images:
As you can see, the body diode is like an internal parallel diode between drain and source. It is functioning as a diode there, no matter what state the MOSFET is in.
If you now apply a sufficient voltage to the gate, the source-drain path starts conducting in both directions.
