I still do not know who took tea at dawn with me

Surely once in your life you have had an experience with some inexplicable event, in which you have been paralyzed with fear. Surely you have ever woken up and can not sleep.
I remember that night, I do not know why I woke up, I tried to sleep but the dream disappeared, I looked at the time, it was 2:35 am, I started looking at the ceiling waiting for the desire to sleep, I got up and went to the kitchen, then I went to the hall, I sat down and turned on the television, I started changing channels without stopping, I stopped looking at the sides and started walking around the house, then I went back to the kitchen, I decided to make a tea, while waiting for the water to heat I felt the feeling that there was someone else walking in the house, I went to check room by room and everyone was asleep.
It was so intense the feeling that there was someone else that I decided to keep looking for the whole house. I went back to the kitchen, I looked for a cup on the shelf, I placed it on the table and I looked at the teapot, I got up again and walked towards the corridor when I heard the sound of the teapot, I went back to the kitchen I went again to the shelf for a cup. I forgot that I had already taken a cup. I placed the cup on the table and made tea, I sat down and I looked at the cup that I had forgotten, I was in front, suddenly I noticed that the chair in front moved as if someone took it out to sit, for the moment I thought that I was dreaming, but I was not asleep, it was as if someone was sitting there in front of me, but, I did not see anything.
I did not feel scared, I grabbed an envelope of tea and placed it in the cup and poured water into the cup that was in front, I drank the tea looking in front of me trying to see who was in front. Thinking, meditating on what was happening, when I finished the tea began a sense of paralyzing fear, I got up and went to my room, I wrapped myself from head to foot scared, until I fell asleep.
The next day everyone asked about the cup with tea that dawned on the table. I told them what had happened. Everyone thought I was sleepwalking.
To this day I keep thinking and wondering who was the presence that sat on the table in front of me.
