Maladaptive daydreaming, also called excessive daydreaming, is when an individual experiences excessive daydreaming that interferes with daily life. It is a proposed diagnosis of a disordered form of dissociative absorption, associated with excessive fantasy that is not recognized by any major medical or psychological criteria.

I think it’s just the name given to “extreme” day dreaming. It’s like having a TV on in the background for me. Sometimes I’ll just blink and realize I’ve been gone for a bit. 😅
