Strange Happenings (2)

Ihave lived in the same house in San Jose, California for 20 years and I have experienced many strange happenings throughout my stay. My house is built near an Indian burial site. There was a large field behind my house that has been built over by houses and a freeway. Before they started building, archaeologists dug up a few sites. I saw actual skeletons behind my house. I don't know if this has anything to do with the weird stuff that's been happening, but I would think that there is a strong correlation.

When my youngest sister was born, she would sleep in a crib next to my mom's bed. One night, my mom woke up and saw an old lady standing over my sister's crib. My mom said the lady looked Indian. Naturally, she was spooked. And for those who think that it is some subconscious thing, this happened before the we found out about the burial site.
When I was younger, I would hear strange noises that sounded like air being sucked through a hose in the middle of the night. There was no logical explanation to the noises.
This also happened when I was younger: I was having a hard time sleeping, and when I opened my eyes, I saw a face staring back at me. I closed my eyes immediately and tried my hardest to fool myself into believing it was a dream.
This experience happened just recently: my girlfriend and I were sleeping in my room and the light just turned on by itself. I have one of those halogen lamps with a dial knob so it would be very hard for it to accidentally turn itself on.
We're moving soon, but we're moving to the new houses behind us.
