To dream of a blowfish represents overindulgence. Being mentally or emotionally engorged. You may be doing something a lot more than is usual or feel that you’ve done something way too much.
Negatively, a blowfish may reflect embarrassment at having done something way too much.
Example: A woman once dreamed of having a pet blowfish. In real life she was expected to perform oral sex on her partner a lot more than he was ever expected to return the favor. The pet blowfish reflected her need to keep him happy by satisfying him whenever he wanted.
