Things That Happen After Death According to Science

#26 Some People Might Produce Moaning Sounds

Once dead, the body undergoes several surreal changes including producing sounds like moaning and groaning. According to pathologists, the residual air in the body formed either due to CPR or bacteria may cause the vocal cords to oscillate and generate noises.

However, experts suggest that this phenomenon takes place only when either the chest is repeatedly pressed or the body is moved vigorously.
