i believe this is about a deranged man fantasizing about cannabilism and (maybe?) necrophilia. the cannabilism part due to “she goes smooth through my body” and he described the state of decomposition the bodies are in (brown and hard, worms in the body, and moldy from the water) he compares these bodies to various reptiles, specifically cold blooded ones, like how a body is “cold-blooded”. we can even interpret where he put each body, one buried in the yard, one in the floorboards (bit of a stretch) and one in a poorly built basement. for the “i cant get your body out of my mind” would refer to him “having his way” with these bodies, or at least getting some sort of twisted sexual pleasure out of his acts. this isnt too far out of the realm of possibilites, as there has been stories of people getting aroused by consuming a body.
