The Shadow
Dreaming of lice: meaning and interpretation
Small things that won't leave you alone
Little worries that multiply and demand attention.
Symbolic reading
Dreaming of lice often shows up when something small is wearing you down more than you'd admit: a thought that keeps coming back, a relationship that drains you, an embarrassment you don't want anyone to see. Notice what you felt. Disgust suggests something you want off you; shame suggests worry about how others see you.
Jungian key
For Jung, whatever feeds on you is a piece of the Shadow living off your energy while you look away. Naming it is how you stop feeding it.
Small things get heavy when they pile up. Deal with them before they grow.
