It was when I was in first year college (2009). Normally before going home, I always drop by my cousin's house so we can chit chat with my cousins (sometimes my other cousins visit also), to enjoy food while watching a movie or sing karaoke.
My cousin's kids, I treat them as my cousins since we are as of the same age and I treat my 2nd degree cousin as my uncle but I call him Kuya and her wife Ate as respect.
That day, me and my cousin Naomi (not her real name) decided to drop by our cousin Elsa's (not her real name) house for a jamming (we are into singing, LOL). When we arrived, we started to set up the karaoke and the snacks. While doing normal stuffs, choosing the next song and eating snacks while the other one is singing, I noticed someone crossed from the stairs to their restroom and he moved very quick.
The set up is their stairs to the 2nd floor is facing the wall in front of it and underneath is the television where we are enjoying the karaoke, so the staircase is behind the TV facing the opposite side. The restroom is across the base of the staircase.
When I saw someone crossing from the stairs to the restroom again and again, I already asked my cousin Elsa. I said "Elsa, I didn't know that Egor (not his real name/ Elsa's younger brother) is here." She said "Huh? No one's here, it's just us. How could you tell he is here?", I replied "I saw some dark skin, short kid like who keeps on crossing from the stairs to your restroom." Then she nervously said "Don't joke about it, Deeyan, we're alone here!" then I said "I'm not joking! I really did see someone over there!" (I pointed the area). Then in a glimpsed of time, Naomi and Elsa are hurrying to get out of the house and because of their action, I got scared too and followed them out of the house. We just stayed outside until her mom came home later that afternoon.
Her mom (my 2nd degree cousin's wife) said that even her best friend Jenny saw someone looking at her face to face while she was sleeping in their living room. She said that the base of the staircase is a portal where spirits can pass through from their world to ours.
