Avoid that neighbour, I'd say.
Good advice, he's dead too. He was a lovely guy though.
Actually that reminds me of one of the stranger experiences I've had. My next door neighbour (who is also now dead but has not been mentioned previously) used to be very deaf, and had a piercingly loud burglar alarm. One night this alarm went off in the middle of the night, so I got up and went to check what was happening. Long story short, checked the house from the outside, nothing amiss, but the alarm was deafening, so I was concerned about what might be happening inside.
I knew the neighbour opposite (the one who told me about the body) had a key. So, I knocked his door, but got no reply. I was left standing in the street wondering what to do, when the front curtains of the house opposite were suddenly drawn back, and the blinds were pulled aside. I couldn't see my neighbour in the window, but it was obvious someone was looking out to see what was going on. I started pointing to the house with the alarm and making key gestures. After a while, long enough for it to seem a bit strange, the curtains and blinds were then let go, as if he was coming to the door. But he didn't come. I should point out here, that he lived alone.
About ten minutes later though, he wondered out of his backdoor obviously still half asleep. He told me he'd been sleeping in the back of his house, was on medication, and just woken up. I told him I'd knocked about ten minutes earlier, and he apologised for not having heard me. I decided not to mention what I'd seen in his window.
As I say, he lived alone, but did used to have girlfriends, who might (although I never remember meeting or seeing them) have been staying with him. But, if so why didn't they wake him? It'd be the obvious thing to do with a blaring alarm and large bloke doing mime outside your window in the small hours.
I'm not saying was anything paranormal, just odd.
