I read a story similar to this so I'll be sharing mine. This happened a few years back, when I was still in college. There were a lot of ghost stories in our campus being more than a hundred years old. I studied in Laguna, which is about a 2-hour drive from home. Because it was that far, I opted to stay in a dormitory. I lived in a studio-type unit with three other schoolmates (Roommate 1, Roommate 2 and Roommate 3).
On our first few nights, we usually stayed up late to chat about days. One time, as I was so lazy to climb up our bunk bed, I pulled my sheets and chose to sleep on the floor instead. Roommate 1 slept beside me for the same reason. As I was slowly dozing off to dreamland, I heard someone knock on the door. He/she was asking me if I was still awake and if I could open the door. Everything was blurry and I don't know if what was happening was a dream but I answered that I was still awake. He/she kept asking me to open the door and even called me by my name.
I, on the other hand, kept saying "sandali lang, babangon nako" (wait, I'll get up). I felt that I got up and walked near the door. But as I was opening the door, I'll hear him/her again asking me to open the door. That's when I realized that I didn't get up! This happened for quite a while until I head him/her talking to someone else and saying "wala, tulog na yan" (She's already asleep). Then I heard the chime of our gate a few seconds after (we lived in a compound, remember?).
The next day, everything seemed blurry. I woke only to find that Roommate 2 and Roommate 3 had already left. Roommate 1 never mentioned anything so I thought everything was a dream. My everyday life continued and I went to school. When I got home that afternoon, Roommate 2 asked me about last night. I was kind of confused. Then she told that she heard murmuring at sleep. She was also not sure if she heard other voices. That's when it hit me. What happened the previous night was not a dream.
I immediately asked a few of our neighbours if they knocked at our unit last night. None of them did. Finally, I asked the guard if someone looked for me last night, since you cannot enter the compound without a key and only tenants have the key. But he said, no one came the previous night.
I told my mom that story when I went home for the weekends. She just said, maybe someone is looking after me but not to open doors for them.
