The crab is the symbol of Cancer, the fourth sign of the Western zodiac. The Sun is in Cancer between June 22nd and July 22nd. Because crabs carry their home around with them, dreaming about a crab is a sign that you possess the ability to create a home wherever you happen to be, and are likely to enjoy a rich home and family life. It also shows that you can work well within a team. However, if a crab bites or pinches you, it is a sign that you are reluctant to accept change and find it hard to let go.
