My Grandma's House

I had never gone to my grandmother's house until I was about 17. It was my first time in Mexico and I was already spooked by the countless rows of crosses on my way to Culiacan Sinaloa. My grandmother's house was originally a big 7 bedroom 1 bathroom house (they had 8 children) but was renovated about 8 years ago into a big 4 bedroom 2 bathroom home. Only 3 rooms were being used by my grandparents, my brother and his wife with their 2 daughters. The last remaining room used to be my uncle's but he moved out. Ever since then nobody stayed in that room, there were rumors of being pulled or cold spots.

Well, when I arrived, I was told by my brother's wife that if I was ever alone and if I heard my name being called from that room, to not go in. Apparently the door would get stuck and you had to wait for someone to help you out (its an old house). I didn't believe her because they tend to joke around with me, but one night everyone was asleep and was babysitting my nieces. It was around 3am and Shrek was playing on the TV. I was still awake waiting for my brother and his wife to get home and then I heard my grandpa calling me. He sounded right outside my door so I quietly said "what?". He didn't answer so I ignored him, thinking he had gone to bed.

About 10 minutes after I heard him call my name again but this time it was a little bit more loud and forced. I got up and went to my grandparents' room, thinking he wanted some water. When I looked in, they were asleep. At that moment I heard my name again but this time it was my brother's voice. I thought he had gotten home and I went to the front door and looked out the window but there was no one there.

Again I heard my name being called but it was my mother's voice, it sounded mad and I realized it was coming from the room. My mother was back in the USA. I was scared because I knew nobody was in there. My grandpa always kept the door locked because of the girls but when I looked in, it was open. The door shut on my face and I ran back to my grandparents' room and slept with them. Call me a coward, but I was not ready for something like that.

I told my grandparents the next morning but they treated it as a dream, even though I made my grandpa get up and check the room. My brother and his wife believed me but had told me to ignore it until I left.

Could it have been a ghost or anything else?
