I was swimming through a bunch of jellyfish and sea fleas
Dreaming about swimming through jellyfish and sea fleas can suggest a feeling of being overwhelmed by negative emotions or situations in your waking life. The jellyfish may represent people or situations that are causing you emotional pain, and the sea fleas may symbolize minor irritations or distractions that are making the situation worse. Alternatively, this dream may indicate that you are exploring emotions that you have been avoiding. It is important to pay attention to the context of the dream and how it makes you feel to better understand its meaning.
