Interesting things for me

I have always been interested in stuffs like déjá vu feeling, amnesia, insomnia or simply human sleeping. One thing that made me surprised was in listening and speaking seminar. I found out that another girl showed interest in déjá vu feeling and study of sleeping too. I was taken aback because I had also been planning to perform these themes but finally I chose Madame Tussaud’s life.

Anyway, déjá vu feeling can be described as an already seen or already experienced situation. Everybody can meet this kind of feeling that can last from 10 to 30 seconds. As I read déjá vu happens mainly to people between 15 and 25 years old. Other age group also realize it but as a person is getting older the frequency of this phenomenon is decreasing. The other strange thing I read and did not understand why it was important factor that people with higher income experience déjá vu more frequently. Besides, the more you travel the more probable you’ll feel it.
One of my personal experiences took place in a seminar, listening and speaking, when I felt for a long time that once I had been there, I had been sitting there sometime in the past. It was so weird feeling.

By the way, the girl I wrote about had said, in relation to sleeping, that 20% of the people dream in black and white. I have never seen a black and white picture in my dreams so far. But the other mentioned vision in dreams, that a person who is dreaming is falling, was dreamt by a lot of people around me as well as by me. A stressful kind of life, anxiety and sometimes circulatory disorder can cause this dream.

The relation between déjá vu and dreams maybe that some scientists say people feel déjá vu because they have already dreamt about that certain situation.
If so, can we predict our events of our life?
