Mollusk are mysterious underwater creatures with hard shells and tender insides. Dreaming of mollusks, your required action is to uncover the mysterious events surrounding the dream. There may be certain events happening around you with no known cause, and you will be effected indirectly. Pay attention closely, and you can crack the hard exterior.
Mollusks in a dream can signify that the dreamer needs to take things slow and take it easy. They may be burning themselves out. For example, you are in a hurry for some reason, but you realize that this feeling is not coming from inside of you, it is coming from outside pressure that you have been putting on yourself. This means you need to back off and relax a little.
