In case you haven't seen it yet, I highly recommend the HBO mini-series "Chernobyl", which is about, well, you know. It's very intense and not for the faint-heartet. I'd say it's more scary than any horror flick, because (despite some artistic liberties taken with the behavior of some of the characters, and the timeline for some events), it's eerily real.
This applies to the field of work as well. Meaning, your boss orders you to show up for a full shift, you show up on time and are absolutely willing to work, and then your boss realizes he has no work for you, your boss has to pay you for a full shift even if you don't work at all.
Fun fact: German law has a concept named "default in acceptance", which postulates that if there is a "service for payment" contract, the party that should provide the service correctly offers their due service, and the party that should pay fails to accept the service within due time, the second party still has to pay the first party even if there was no service delivered.
I've experienced sleep paralysis with ghostly images and similar things in the past and can snap out of it through moving my fingers. I've definitely hallucinated before and members of both sides of the family have had similar experience, some suffered forms of mental instability in two cases schizophrenia.
