The raccoon is a survivor and can take advantage of many situations to get its needs. So it can be a bandit type attitude in us, so it can be about thoughts or feelings that are like looking in dustbins and scrap heaps in your life instead of giving of your best and getting the rewards you deserve. So it might represent the fact the you do not rate yourself highly enough, that you have a poor self-image, or even that you are or like being a rascal – or even an amusing and entertaining friend.

People associate raccoon with many things, for instance the face marking of them is like a mask, but this does not mean if you dream of them you are hiding behind a mask. Better to ask yourself what mammalian aspects you can see in yourself. We all have a section of our brain that deals with our own mammalian instincts. See Mammal Brain
Because the raccoon can use its hands to do many more things than cats or dogs it has developed more strategies to survive, that’s why it can represent the survival instinct we all have in some degree. In the USA it can carry rabies, so it may be you have associated it with danger of infection.
