Started Seeing Shadows

First time poster here. Love the site but anyways I have got a story to tell.

Ok so recently there have been some strange occurrences happening around our house. We moved into our house in 1993 and bought it brand new. Nothing paranormal ever happened until recently some strange unexplainable things have been happening.

The first time I had paranormal experience was when I was sitting in my living room with my sister. I saw something moving in the hallway. I turned my head to look thinking it was mom, only to see a shadow walk across the hallway right through the closet door. I asked my sister if she saw anything and she said she wasn't paying attention to the hall. Nothing too spooky so I blew it off and basically forgot about it.

A few weeks' later things started getting to weird for me. Everyday I would see shadows moving, running, or floating around the house. Sometimes I would look and the shadows would just zoom across the room and disappear. Other times I would stare at one and it would just float off. The shadow (s) would always appear in different shapes and sizes.

I think I'm the only one seeing these and if not my family is hiding the fact that they're seeing them too.

The other night after watching some TV I decided to go down to the basement and go to bed. My sister's room is right across the hall from mine. When I turned the corner I saw a shadow zoom right through my sisters door. Immediately after I heard what sounded like my sister scream. I ran to her room and opened the door only to find her in a deep sleep. That really freaked me out. But it gets weirder.

Later that night when I was trying to fall asleep in my room I was startled by a pressure on my bed. You know like it felt like there was someone sitting on the edge of my bed. Then I started to hear a noise that was like gargling and hissing. It's hard to find words to describe the noise but it had me scared out of my socks. I was stricken by fear and to afraid to look and see what it was afraid that it was something I really didn't want to see. After about 30 seconds it stopped and I looked to see nothing there.

My room felt cold but that could just be because it's always pretty cold in my basement. I was so startled by this I haven't slept in my room since and I still see the shadows. I wish all this would just go away.

Any ideas or comments welcome.

Ps, all this kind of started happening since my life has become more stressful. I have been fighting with my parents a lot and I have been very stressed from other things. Maybe this could be attracting these things? I don't know just throwing that out there.
