Yor are not crazy,i lived with my sister for about a year and her dog layla a peekapoo and i got real close i was going through a hard time and she was there for me that whole year,her health was failing so my brother in law put her down and my sister in i heard her all the time going up and down the stairs and at night she would once everyone was in bed go around and check on everyone it lasted about three months and we did not hear her anymore.
I think she was making sure everyone was ok and then she crossed the bridge once she was ready.
