Green Haven

At my grandparents old house in Green Haven, there was a vent that was on the wall as u went up the stairs to the pool/ game room. When my cousins and I were little we both woke up to go down stairs and there was a green figure of a Victorian type lady. She whispered “don’t go down stairs, he’s waiting” I remember me and my cousin Steven looking at each other and running to tell my Grammy and grampy. They went to investigate and found nothing: when we returned upstairs there was a leery feeling. All growing up we would always see her eyes in that vent at times. Once we got older and I had kids I never mentioned the green lady. And one night my boys were having a sleep over up there and came running down in the middle of the night crying about the green lady! I never found out who or what she was. But fully know she existed
