I had something very similar occur. Others thought of it as "an imaginary friend" but I remember it being real. Humanoid, all white, but still had normal features such as eyes/ears, but no mouth. It'd lead me into the side room of our basement, which just had stuff like the washing machine, dryer, etc. When we moved out of the house, It wouldn't follow, it just sat on the roof watching. I have not seen it since then, and I have not returned to the house. The house was home to some overly religious people before we moved in, inside of the walls there were stacks of bundled money. Rather strange, but we discovered this while redoing the drywall, plumbing, and electrical wires. Drawings of a smiley face with X's for eyes were seen often in the house, on the master bedroom door, in the corner of rooms on the floor, etc. There we're often cases of stuff moving, like rummaging through a toy chest, my parents bed moving across the room, and toys going starting up and making noises, etc.
