There is no special significance except that the raccoon was either looking for food or shelter.
Raccoons get part of their water through the food they eat and the rest by drinking it.
The raccoon primarily uses its sense of smell, along with its sense of hearing to find food. It uses its sense of touch to locate food in water.
Raccoons forage for food - they search for it following their noses and using their fingers to feel for it in water.
Raccoons are present in communities because they are wild animals, and they are always looking for food. They go to neighbourhoods to garbage cans where people leave tracings of food that they didn't eat. If you see a raccoon in your backyard or something, don't scare the poor thing away! It's just looking for food. If you go outside and it runs at you, you run too. But if it runs away, it's a raccoon WITHOUT rabies, and a raccoon looking for food to feed him/herself, and their family. The raccoons steal the food, they have a black line across their eyes, and that why today, robbers wear a black mask to immitate raccoons. The raccoons didn't copy them!

Raccoons frequently forage for food in shallow water and may become dinner to a hungry alligator.
If there is no escape, no food and no water they could only live a few days, depending on the ambient temperature. After that the house is going to become quite stinky as the raccoon decays.

Raccoons eat anything even remotely edible - plant or animal - so it is unlikely a raccoon would be unable to find something to eat. They will scavenge trash bins for food and eat pet food if it is left outdoors.
