Nightmare #2

A scientist working for the government is devising a way to keep bodies cryogenically frozen to endure space travel. One day the temperatures have dropped below absolute zero causing the bodies that are frozen to break apart. It is then revealed that beings from an icy dimension have entered our universe and caused the subfreezing temperatures. They then reassemble all the broken bodies and turn them into misshapen invulnerable monsters to help them conquer our dimension. The scientist is able to increase the temperature to the point where the misshapen monsters become perpetually frozen.
