Mild forms of feeling disconnected happen to almost everyone during normal daily activities.

You do not need to go through a major crisis to feel a disconnect. Everyday moments of spacing out are actually mild forms of dissociation. For example, you might get so lost in a good book that you lose track of the room. Or you might drive all the way home on autopilot and realize you do not remember the turns. Your brain naturally slips into these states to save energy.
