The wife and I had said our good nights and I was facing one way (towards a wall the other side of which is our backyard). She was facing the other way (we were back to back) in front of her a short distance was the door to enter our room.
Right through the wall came a gentleman about 5 foot 11 inch tall wearing a grey plaid shirt and grey pants. This man proceeded to walk past our bed (it was the foot of our bed) as I laid frozen except for turning my head to follow where he was going. As soon as he had walked past (like midway) our bed and reached the point where my wife, facing the other direction, might have been able to see him by way of peripheral vision. Sure enough, she did catch his slow movement past our bed.
As she turned her head to see him she could also see, looking past her shoulder, that my head was also turned as I was watching the dude too. Our eyes met with the same WTF look in them. As we both then watched as he took about five more steps, then turned around and walked out through the door on another wall which also led to the backyard. Walked through the door, did not open it.
The way it went down with us being back to back, then her looking back at me over her shoulder, still laying back to back. We saw the same dude exactly... But that's all we know, he has not returned yet to my knowledge.
