About 7 years ago, this event took place in my house. My grandmother was really sick, she was in bed with oxygen to help her breathing. She was very devoted to God, great woman and always put family first.
I was ending my senior year and I was very close with my grandmother. I suggested to my mother that we could put a mattress on the floor next to my nanny's bed so I could take care of her if she needed something through the night.
One night I was in the living room watching some TV before bed, time was 22:30. My mom said goodnight and went to her bedroom. About ten to 15 minutes later I was getting tired so I turned off the TV and then the light of the living room. The only light on was from my nanny's room with the door opened a crack across living room. As soon as I took about 4 steps, I saw someone ducking in the middle of the room. "My mom is playing tricks on me", I thought. But as I took more steps it didn't look human. It was darker than the dark, on fours and features of a human body, except it was thin almost like bone appearance. I saw its profile of face, because it started to look towards the crack of light from nanny's room. It was long and bone features with some spikes on its head. I froze and stayed looking at this thing and didn't took my eyes off of it. In a matter of seconds it started to move towards me on all fours very fast, and right through my legs and vanished on the furniture behind me. I ran to the room, and didn't tell anyone.
A week later about 22:10, went to nanny's room, closed the door quiet behind me because she was sleeping. I started writing on my journal and I heard a "click", very distinctively. Didn't pay that much attention, after all house is quiet and you can hear noises. I started to see my nanny sleep, and I noticed that she looked uncomfortable, like she was having a nightmare. So, softly, I get close to her and move her arm gently to wake her up. "Nanny, Nanny, wake up", repeatedly. She opened her eyes, very disturbed and screamed, "Lock the door! Lock the door now!" No hesitation, I got up and immediately turn the lock and turn knob to check if it was locked and realized I was opening door. That "click" I heard minutes ago locked the door. I asked nanny what happened... "This dark creature was sucking the air out of my mouth." I cried, and was speechless, grabbed bible and read to her Psalm 99. This still haunts me and makes me think if that thing made my nanny more sick. She passed away 2 weeks later.
