Dreaming of a crab can also be an indication of fear or inner emotions causing tension, especially within the abdomen. The person dreaming this dream may be afraid due to guilt or of sensual pleasure. This dream can also be an indication of the personality trait where the dreamer has a hard exterior, but possesses inner softness.
A crab that threatens others is a sign that the dreamer wants to inflict pain on others. It may also indicate wanting to keep hold of things, particularly holding onto things for too long, or chat causes pain either to the dreamer or others. The claws of the crab can indicate clinginess in the relationship, or a desire to hold onto something.
In the book, Dreams and Nightmares, Hadfield (1954) gives the idea that spiders, crabs and vampires in dreams are a projection of a person’s feelings experienced through orgasm. Dreaming of a crab is indicative of the visceral and abdominal muscle spasms that cause the body to grip; the spread legs and soft abdomen of the spider show the relaxation caused by orgasm, and the fatigued feeling that results is seen in the image of a vampire, which has ‘sucked the lifeblood’ from a person.
If the crab nips you, it’s a sign of pain (either psychosomatic or physical), or perhaps illness, that is the result of the dreamer being overly tight or self-protective.
Example: If I tell my girlfriend that I would rather not have fireworks. She keeps insisting that fireworks are wonderful. I tell her to buy it herself if she wants it. I offer for her to hold the crab because it is trying to nip me. She says she’d rather not. I take it away and try to find a place to leave it or get rid of it.
Example: After going upstairs, I felt inclined to fully undress, and admired myself in the mirror for a bit. My body looked built, as if I had been putting in some effort – which would be a good description of my sex life lately, from all the orgasms. My arms were huge. This reminded me of the fiddler crab and it’s giant claw. I thought of my arm as a strong and resourceful tool or piece of equipment for me to carry around. It looked bulky.
