Grandmother?

I am very new to this site and I thought I would submit this Experience I had.

I was 11 at the time. I have a history of Chronic Migraines. I had come home from my friend's house because I had a migraine. I came home took my meds and lay down. Later, I woke up and came downstairs to find that my parents have gone to bed. So I took advantage of that and plopped on the couch to watch some TV. Being so curious about the paranormal, I found myself Watching Most Haunted on the travel channel.

About a half an Hour into the show, I felt spooky like someone was behind me my Cat Leo, Was sneak attacking me so I started playing back with him. That led me to look into the computer room where my grandmother's urn is to this day. My grandmother had died in July of '06. As I looked into the computer room, I saw a white figure standing by our family computer. I stood there staring at it for at least 1 minute and hid under the blanket on the couch for about 5 minutes then ran upstairs.

Another time, I was 12. I was on my family computer listening to music and I had almost all of the lights on downstairs since the previous incident while I was on aim, (at the time my mom had this fresh eggs sign for decoration) the sign fell off the wall and it was totally secure on the wall. It scared the living poop out of me!
