What Landed On My Bed?

This story happened at around 9 in the morning. I am using the master bedroom alone because no one dared to use it because it's too big to clean LOL. This happened in our house, the one that we are still living right now. That is our permanent address and I am currently renting an apartment with workmates behind our office building, but I still go to our house when I have business there, especially during day offs and or just to visit my mom and the rest.

The event occurred in my room last 2012. The room used to be my grandparents' room when it was built (the house is my grandparents', then my family are the ones left to live with my aunt on the other room and my uncle in the only room near the living room). When they passed away, it became my family room. It had 2 beds before one that my grandpa owns and one is my grandma's. It has 3 beds when I started to own the room. The bed that is on the right side wall when you enter the room belongs to my grandpa (who passed away when I was 3). I use it when the sun is up because my bed which I placed across the door will be hit with the sunrise and will get hot later on. The third bed was owned by my grandma (the biggest and the one I used before when I was younger and when she passed away a year after my grandpa died) can be seen at the very left side of the room in front of our closet.

I was about to continue to sleep after I transferred, but when I'm about to drift off, I felt something that stepped to the bed which made my head fall to that part because I'm sleeping facing left side, on the wall (I always sleep sideways for some reason I will share soon). In my mind someone from my family stepped to the bed to grab something above me, but I quickly remember that the elevated divider is on my foot part. Then after I felt my head fall to the part of the bed where someone stepped on it, I froze and stood up immediately rushing to the door, but I was shocked to see my older sister (who at that time was living with us already. She went home to our place after she was sent to Manila for 9 years when my dad died in 2011) leaving her room across my room to go downstairs. She looked nervous then she awkwardly laughed. I said "What happened to you? I felt something stepped to the bed while I'm drifting off to sleep so I rushed to the door and was about to go downstairs." She said "I heard footsteps running so I was planning to rush off downstairs." Then we paused for a second and we both rushed downstairs. My older sister has her own experiences also before when she was younger and was not sent to Manila and got married yet. As of now, please let me know your thoughts. Thank you.
