In the past few days:
me and my grandma were the only ones home I heard a female voice speaking, I thought it sounded like my sister, and then my grandma yells out 'what did you just say?' I told that I thought it was her talking.
me and my siblings were in the loungeroom, my grandpa was asleep, nan is in hospital. our stairs are loud, you can clearly hear when people are walking upstairs. we all clearly heard someone walking up the stairs. it was clearly step, step, step, step, not a house creaking.
my brother and grandfather were in the granny flat downstairs, my sister was out. I was walking up the stairs when all of a sudden there was movement at my eye level, then clanging, and 4 steps in front of me I noticed something bouncing around. it stops, I pick it up, and it's a 50c coin
I was home alone I walked down to my bathroom. as I was walking around the house, I was turning off unnecessary electrical things. my sister's room, the toilet room, and the bathroom are in a U shape, with the bathroom and my sister's room facing each other. someone had left the toilet fan and light on. when I turned them off, I was literally standing in my sister's room's doorway. She has a ceiling fan, and it's really loud, like you can hear it in all the bedrooms, loud you can't miss it (this is important later) it was definitely NOT on. I went and had a shower, and as soon as I turned the water off, I could hear the fan going.
I can sorta explain away 1 and 4. maybe someone was talking outside, and maybe I just didn't notice the fan... but I can't explain away the middle two. I am alone and scared. if anyone can think of how they happened, it'd be very helpful!!
