Dead bodies can appear to move after death due to several post-mortem processes. These movements aren't caused by any supernatural forces, but rather natural bodily changes.
Post-Mortem Movement: A Natural Phenomenon
The seemingly spooky movements observed in corpses are largely due to the ongoing process of decomposition. As the body breaks down, several factors contribute to this:
-
Ligament and Muscle Contraction: As explained by Wilson in an interview with Agence France-Presse on September 17, 2019, the movements relate to the process of decomposition, particularly the drying out of ligaments. The shrinking and tightening of ligaments can cause limbs to shift or appear to move. This is a passive movement, not an active one.
-
Gas Buildup: The decomposition process also produces gases within the body. This gas buildup can cause limbs to move unexpectedly as the gases exert pressure within the body. This is a particularly notable factor in bloating, which can drastically alter the body's appearance and potentially cause movement.
-
Gravity: Simple physics plays a role. As muscles and ligaments relax, gravity can pull limbs into different positions, giving the impression of movement.
Debunking Myths
It's important to distinguish between actual post-mortem movement and other factors. Sometimes, perceived movement might be attributed to:
- External Factors: Animals or insects interacting with the body could cause minor shifts or disturbances.
- Misinterpretations: In poorly lit or otherwise challenging environments, slight shifts in perspective or lighting can make a still body appear to move.
In conclusion, the apparent movement of dead bodies is a natural consequence of decomposition and physical processes rather than a paranormal phenomenon. The shrinking of ligaments and gas buildup are key contributors.
