Some more reliable metaphorical (“dream logic”) correspondences:
Mirror = introspection, self-concept
Vampire = psychopath (doesn’t appear in a mirror = no capacity for self-awareness)
Trapped in a mirror = Jungian introversion (i.e. hyper self-aware neurosis)
Shattered mirror = Schizophrenia, ego death
I used the weekend poorly so it may be a slow week around here.
