Bodies in a row, covered in canvas

Long row of covered bodies in front of me.
Ghost appear in many form


Every night,the spirits appear, this time, there a long row of look like humans bodies covered with a long piece of canvas. Just like the row of ancient Chinese coffins and was in the same place, this time were bodies. Just like the coffin I sometimes can see and sometimes cannot see them, also for sometimes until another thing appeared.

Midnight shift in a spirits infested warehouse!!!
