Man near the blinds

Last night DS was awake at stupid o'clock (again!) and told me there was a "man at the blinds" :o I asked him a couple of questions but he didn't really tell me much except to point to exactly where he was. I often feel a presence around me, in all the houses I've lived but even after he said it I didn't feel anything.
Is anyone able to tell me who he is?
There are 2 men in our family who have passed and we've just moved into a new house where an old couple had lived. The man has passed away and the lady is now in a nursing home.

Eta- he was also telling me he could see a diamond window. He knows his shapes very well and the only window in the room is a big rectangular one, so I'm not sure where that come from either...
