Can u explain this please? (ghostly)?

I went to an old abandoned warehouse structure with a friend.

It was dark in the warehouse, me and my friend brang torches

There was a small room in the warehouse, like an old office space.

I shined my torch toward the end of the room, there was a shelf with something on it.

we took a closer look at it, under torch light we saw

a pile of dead flies and a condom on top

we then looked around again

there was a piece of paper on a shelf close by, i picked it up

on it there was writing, which said-

"need nappy, dummy, blankets"

i then turned it over

on the other side it said-

"none of this now needed, baby dead"

whats going on?
