I thought this was just my imagination running wild but I am now convinced it is not.
I have been waking up between 11:50 pm and 12:53 am, but not every night. It seems to be the nights I drift of to sleep as soon as I hit the pillow. I wake up to someone sweeping my garden. At first, I thought I was just imagining, due to being tired. The first few times I heard the sweeping, I managed to go back to sleep. Fobbing it off to just hearing things. However, the last couple of times I have woken up, unable to go back to sleep, I have listened carefully and there is definitely someone sweeping my garden. They start by the patio doors and make their way towards the windows near the bedroom. It is one of those gardener brooms, I know this from the sound, very hard. When the sweeper gets to the last window, the sweeping stops.
On a couple of occasions, I have heard the chairs being moved, so the slabs can be swept and then moved back. Just recently I have heard someone tapping on the bedroom window. The tapping goes on for about one minute and then stops. The tapping has been going on for about two weeks.
I thought I was cracking up but I have noticed Inka seems to stare at the window a lot. She will just sit and stare at the window. Having said that, I have been looking at the window a lot as well when night falls, and occasionally during the day. I get a very uneasy feeling.
