When I was young, about 7 or 8, I can't remember the exact age, I was in a swimming lesson, in the adult/deep pool, with my brother and some other kids around our age. Suddenly, I felt a hand pushing my head down into the water. I struggled and tried to get up but I can't. At first I thought it was my brother who pushed me down the water, playing a prank, as he was just beside me. But I was out of breathe and was unconscious. But after a long time, it feels like about half an hour, I suddenly regain my conscious and the "pushing" feeling on my head was gone. I immediately get out of the pool and took a look around. The clock showed that the time had gone only a minute and the kids in the pool just talking to each other seeming like everything is normal. I told my mom after the swimming lesson, but I didn't told her about the time passing, and she confronted my brother and my brother said he was talking to his friend and didn't see me struggling in the water.
In 2010, I had a dream that my friend had been bang down by a car. Then a month later I was being told that my friend had passed away in a car accident.
Then later on that year around the time my great grandmother passed away, I had a sudden fever but I was feeling well that day.
In 2011, I started having deja-vus and one time, I was suppose to meet my friend at McDonalds in the early morning at 6.15am. The way to McDonald had to go through a small walk-path which is surrounded by trees. While I was walking, I felt that there's something up the tree, I took a look and saw a white bundle, sized of a full grown adult, up on the tree. I stopped and wanted to take a photo but I had a negative feeling so I didn't took it. Then after meeting my friend, we walk back the same walk-way I walked earlier on and the white bundle was gone.
A few months later, I went to the toilet at school and suddenly heard a lullaby but I took a look around and no one was in. I was so freaked out that I ran back to my class and my teacher asked me why's my face so pale.
This earlier part of this year, my hand phone strap drop on the floor and when picking up, I had a feeling telling me "Something bad is going to happen" and a few hours later, my relatives called and said my grandmother is in the hospital and might pass on anytime. A few days later, she passed on.
This week, I had some simple dreams that came true. For example, I dreamt that I went for a swim and the next day, my mom asked me if I wanted to swim with her and I did.
What does this means? Why do I keep having this type of deja-vus/feelings/dreams/experiences? Is it negative or positive?
