Having had episodes of extreme paranoia and panic attacks from mental conditions caused by chemical imbalances, I sympathize with this man. If this man truly believed what he thought was happening to him was true, then he actually lived that event.
Mostly we only hear of the high profile cases of temporary mental breakdowns such as what happened to the woman who played Lois Lane when she disappeared and was later found as a homeless woman not knowing who she was.
Unfortunately this sort of thing is increasing in our society due to the conditions we currently live in.
I am not saying we should not scoff at such stories or even get a chuckle or two over the absurdity of them. Just keep in mind that this can happen to anyone at any time.
