This is so interesting to me to see other's replies. I can definitely relate to the maladaptive daydreaming- often I would go into these meditative states, detailing scenarios I wished for myself in the future, usually these involved some form of love relationship- the only thing I found pleasurable enough to distract me from the inherent horror of life. Generally the subject was a real person I knew, so I would project my feelings onto this character in my imagination, and it would feel so visceral, like I was loving them in real time. These exercises would only contribute to intensify my eventual despair, because in real time, the people I genuinely loved were the ones who ripped me apart the worst. Other than those daydreaming states, my mental conversations involve, "I", "you", and even "we". Also, this may be a result of my past manic conditions, but sometimes I converse with an "other" in my mind.
