Something Bit Me And Haunted House

I'm a sixteen year old girl and I live in a house along with my grandpa, grandma, and my mom (my parents split up a long time ago). The house I live in is a family house (our family had lived here from time to time) and beside our house is my uncle's house, he lived with his wife and his two children, Sarah and Joe (these aren't their real names). My house is kind of haunted; there are few spirits that lived here. Let me tell you there are 5 spirits (or maybe more I don't know).

1. A woman ghost. She often stays in the backyard and sometimes flies off to my neighbor's balcony. I once had her picture in my old mobile camera; she was in my bedroom, quiet tall and had this long black hair that covered her face. I had no idea how this picture got onto my mobile, no one took it, still mystery though.

2. A ghost girl. This little girl often walks pass my bedroom and plays in my bathroom sometimes. She once whispered at me, I'll post it in my other story later.

3. A child ghost. I have no idea whether it's a girl or a boy, but it likes to play/messing up with toys but puts them back after she/he finished playing.

4. The mute guy. He used to posses my uncle and this ghost wasn't able to talk.

5. Unknown ghost. This ghost, I don't know what or who this is but it likes to scratch and play (make noises) with my bedroom's door.

My mom told me when I was a child my grandpa used to have this ability to expel bad spirits. He expelled the woman ghost a long time ago but then she came back after a few years.

Recently, a week ago I had sleep paralysis at night but I shrugged it off cause it happened to me many times before. In the morning, my mum told me she had this sleep paralysis, she said she was on the phone last night and fell asleep in the middle of the conversation. When she tried to speak again, she couldn't and something was covering her mouth she wasn't sure what that was and then I realized it happened to me as well, at the same night. My grandma suddenly told us that last night she was screaming like "Satan! Satan! Satan!" in her sleep, when my grandpa woke her up she still screaming. It was odd.

At the same night my cousin Sarah told me she also had odd things happened to her too. She smelt a scent of a flower, the scent was strong enough to scare her off of the bathroom (it was in her house's bathroom) when her dad checked onto the bathroom, the smell was gone. Her dad then spent the night watching football match on TV, at midnight he heard something from outside of the house so he went to check what that was. He went outside of the house and saw someone stood in the middle of the street, it was a woman with long hair she wore white gown or something like that. She just stood there and did nothing, in the middle of the street. My uncle freaked out and ran inside his house as soon as possible.

Two days later I went out with my friend to the mall, it was just like usual but when we had chat on the mall food court, and one of them asked me "what happened with your leg?" (I wore short pants) I didn't know what she going on about until I saw my left leg. There was a mark as if someone or something had bit me, I still have it on my left leg right now, its bruised and people who have seen this mark said this wasn't human who did this, it looks like something with fangs (all its teeth are fangs and sharp) did this.

Is this has something with the woman? Or what it might be?

Please help me, thank you for reading.
