I keep having distrubingly vivid dreams about my wife cheating on me. I was having them while we were dating and they stopped

. At first i atributed them to my thoughts of perinoya. because i'm deployed and like 6000 mi away
However last night i had the most vivid one ever..
It was a recorded video on DVD
It started off with sone black guy poimting the camera at his face; he was smiling.
then it moved down to his abs he had a six pack ...
then it moved to her face she was facing him on the front left side of the screen...; she had a blank f*** you facial expression... like haha f*** you motherf***er i'm cheatging on you...
Then it moved to his penis... He was standing and she wa on her knees... They were both nude
can any body tell me the meaning of this...
