The bed that swallows

Heard news on the radio: A Florida man was swallowed up, bed and all, by a sink hole beneath his house. He was never found.

Associations: The bedsheets sometimes have a few blood stains here and there. It took me some investigation to find out where the blood came from (not from me). At first it seems a bit gruesome.

There might be enough here for a short horror story or something, with bed, sleep, and dreams/nightmare.
