Your trying to swim you go to the bottom of the sea or swimming pool but when you have drowned (died) you rise to the top ?

After a couple of days, bacteria will start to decompose your corpse and release gasses that make you bloat up, thereby making you more buoyant so you rise to the top.
Lesson learned: if you kill someone and dump the body in water, be sure to weight it down with something.

If I am laying flat on the surface, I float quite well. Your body mass is an issue, as well as your weight, versus what you displace are factors of float or not. Most people float quite well. It is when air sacs, such as the lungs fill with water that they sink. So far as the return to the surface after drowning, that is nothing more than the decay of the body. All of the bacteria go nuts feeding on your body and producing gasses such as methane, sulfur dioxide, and carbon dioxide, and eventually, their source of food becomes buoyant again due to their feasting.

When people die, the bacteria in their gut, etc goes crazy and starts multiplying by the zillions, this causes decomposition and creates noxious gases. The gases make a dead body/animal bloat and gives bouyancy to the body so that they float. Usually they sink first, then as decomposition takes over, the body rises to the surface

It is due to the accumulation of gases formed as a result of decomposition.

No. I've never been dead :)
