I didn't realize it because I didn't even know this was a thing that could happen. At least not without being infected with malicious code or hacked.

[The fact he did this to himself somehow? That's extra horrifying. He doesn't even have anyone to blame for this.]

What causes this other than nebulous emotions because I would like to avoid this ever happening again. If that's even possible since I presume if it was that easy you wouldn't spend a substantial amount of time in this state. Ideally neither of us would ever have to deal with this for.. forever would be a decent amount of time I think.
