We can absolutely imagine, there's no problem there (unless one both lacks imagination and the ability to think outside their heads). It's just likely to be more inaccurate the less experience you have in that and related areas.
I have also at least thought about some of the stuff you mentioned coz I have/had a lot of characters and a lot of the poor buggers end up in some interesting situations
I'm completely unsurprised that "take care of/make some time for yourself" got taken to the point of idiocy too.
It is this side. I am looking at it from a more philosophical side of things. We can imagine anything - but the accuracy of it will vary :)
We are idiots :D
