I watched several shows on DVD this afternoon.
I began with the remaining shows on disc 4 in the MEDIUM set which I had begun last night.
This one involved a man who smothered prostitutes and then buried them in the desert. Allison happened upon the man at a clinic having an MRI done after she slipped and banged her head on the floor. The only thing was the man at the clinic was so friendly and non-threatening. She got no hostile vibe from him at all in person, only in her dreams. What's more, when she dropped hints to him about prostitutes and the desert, he had no reaction of fear of discovery which left her even more perplexed.
Good little mystery.
