"Fiend Without a Face"!!! One of the great, freaky 50's horror movies that scared the crap out of me as a kid on late night TV in the 60's-70's ("The Fly" and "The Thing" were the other two).
IIRC, some nuclear mishap causes people to die, and their brain and spinal cords come back to life, and fly around and strangle you, then feast on your flesh. A family is holed up in a house and these things are trying to bust in, flying through the boarded-up windows, down the chimney, etc. Serious nightmare stuff.
Everybody's killing them left and right, with axes, guns... the effects are surprisingly gory and gross for the 50's. Recommended!
