1000 uses for severed heads

Last night I dreamed about severed heads. I was running around the backstreets of some houses, trying to work out the time since a head was severed from a body. Just before i woke up I had figured something out involving formaldehyde and a needle.

I wrote the above paragraph about a week ago. I have already forgotten the dream, but the text shocked me. What caused the dream? I had been reading Truth Dare Kill by Gordon Ferris. This is a great cheap book on the kindle about a serial killer set in 1945. The hero is a private detective, who suffered a bad head injury in the war. His own paranoia starts to rise as he searches the streets of London.
