My paranormal experiences

A theory! [Creepy]

I know. It's crazy. I made up a theory with my house.

What if 'whatever is inside my house' caused the sicknesses and deaths?

I've actually been thinking about this for a while now-and I have proof for this crazy idea. I know that something else is inside my house other than my family. My mom heard foot steps today and I keep feeling and seeing water drops hit me! Back to the theory:

I know for the past few years, I've had multiple deaths and other sickness related things happening within my family. Those family members all went to my house before getting sick.

1. My aunt. Three years ago, she got a terrible cancer, and died just over a year ago. A few weeks before she got diagnosed, she stayed at my house for a week or two.

2. My grandma. At the beginning of my grade 10, she was staying over for a lunch/dinner at my house after a gathering. She was fine! The next week, she suddenly got sick and passed away a few days later. She was in her 90s, but who knows? She was really healthy for her age.

3. Another person in my family. They live in the household. They have suddenly gotten sick, and things keep going wrong (diagnosis).
Edit [Jan 2017]: This person, who was one of my parents, has also passed away in this household, (ALS/Oct 2016).

Is it just bad luck within my family, or is there something interfering? I don't know, but this has gotten me thinking.

Edit [Jan 2017]: I've already mentioned the first two owners of this house in the first chapter, I think.
The first family: The wife had some kind of nerve/ muscle disease, but I don't think she passed away in this house.
Second family: Son committed suicide in basement.
Honestly, this all fascinates me.
