Dreams are weird, there’s no doubting it. They usually fall in a sort of uncanny valley, where the events that transpire feel realistic enough to be believable in the moment, but are much too fragmented when looking back. Thus, dreams may have people who are recognizable, or places which are familiar, but the exact details do not match. People might have different personalities, shifted voices, or even different appearances. To find out why this is, we have to look at the root cause of dreams.
