How will you react when you see a declared dead man suddenly wakes up inside his body bag?

Walter Williams, a 78-year-old American, was actually declared dead since Wednesday evening after medics failed to find his pulse.

When he was about to be embalmed inside the Porters and Sons Funeral Home, workers suddenly noticed movement inside William’s body bag.

True enough, Williams is not dead yet. Authorities point to a defective pacemaker that could have caused Williams’ pulse.
