stayed at a mates house a few years back.He lived in an old post office that had been converted to being one big house so it had two flights of stairs and two ends to the house if you get my drift.Over the years that they lived there they had tried to rent one end out (lodger stylee) but it had never worked out,the lodger would allways clear off after about a month.
so i was staying with them for a week with my mrs and we took up the empty end of the house.
Every bloody morning at 2:20 i would be woken up to the sound of someone running up the stairs (in my end of the house)then stopping, next would be the sound of something being thrown back down the stairs.something small like a wooden ball.
happened five nights in a row, on the last night i made a dart for the landing as soon as i heard it but the noise stopped as soon as my feet touched the floor.
when i told my mate it freaked him out a bit because 2:20 was the time of night that his 3 dogs would join them in bed.
never had any other weirdness like that but it still baffles me because its hard to put the noise down to anything else.
