First, apologies for not being on and responding sooner. Life has been about two weeks of holding my breath, so it's not exactly been fun x_x

The spiders are your animus, the masculine side of yourself and the primal... Though since there are two major male figures included, I'd say more primal than gender based. Since you dislike spiders to begin with these are negative aspects about yourself...about your core self...that you dislike. You attribute the spiders to a hallucination. This backs up the concept that you link them to your mental illness. Everybody else in the dream is apathetic to your dilemma. How does that relate to you? The people are all you, typically related to traits you perceive as shared between you and the person you're dreaming of. How are these traits keeping you apathetic toward your own inner dilemmas? In the end, you are seeking the validation of someone else regarding your own problems. Are you taking this outlook with your therapist? Are you taking this outlook in general? The irony in the dream is that while you're seeking others to validate your fears in the dream, you are doing exactly what you need to do in the waking world unwittingly - you need to seek the validation from within yourself.
