(Self dx autistic here) My thoughts are usually full sentences that either sound like me talking to myself, or me having a conversation with myself as another person (I'm one person tho, the conversation style of thought helps me work through problems). Otherwise my thoughts are very visual, usually when trying to describe a concept. Numerical values and times and my mind (as a physical object) all have a semi-specific shapes and/or locations-- I think this is a synesthesia thing.
When I say me having a conversation with myself, I mean like one part of my mind will take one side of the problem at hand & another part of my mind will take the other side and I’ll have a debate with myself. This helps me weigh pros & cons and make choices.
