What to do if you were buried alive in a coffin
1. Do not waste oxygen. In a classic coffin there is about an hour’s worth of air supply, maximum two. Inhale deeply, exhale slowly. When you inhale, do not swallow, because it causes hyperventilation. Do not light a match or a lighter, it takes oxygen, but it is not forbidden to use a flashlight. Do not scream: screaming intensifies your panic, which quickens the heartbeat and your breathing, and hence the air consumption.
2. Try loosen up the lid with your hands; in the cheapest coffins made of fiberboard you can even make a hole (with a wedding ring, or a belt buckle ...)
3. Cross your arms over your chest by grabbing your shoulders, pull your shirt up and tie it with a knot over your head; by hanging like a bag over your head, it will protect you from choking when the soil gets inside the coffin.
4. Try knocking the lid off with your legs. Cheap coffins sometimes break just under the weight of the soil immediately after they are buried!
5. Once the lid breaks, direct the soil from your head to your feet, and when it gets tight, attempt to press the soil with your feet in different directions.
6. Whatever it takes – try to sit down, this way the soil will fill in the empty space and will move in your favor, do not stop and continue to breathe calmly.
7. Get up!
Remember: the soil in a fresh grave is always loose and "fighting with it is relatively easily”; it is much more difficult to get out in the rain: wet soil is denser and heavier. The same can be said about clay.
