Enter the zone, if it is night (ghostly house at top of hill) then exit and reenter and it will be day and the house will be rubble. up the hill on the left is a pavilion, note the positions of the statues. Leave the zone and reenter, should be night again, return to the pavilion and the statues will have moved and be ghostly, and interactable. Move each to the position that they were in the day (tis actually just 4 clicks for each), and the house will materialise. Enter, read the note, sleep in the bed. Say hello to your good old super best friend.
