Many people experience mind body separation (Nama rupa Paricheda Nana) without realising that they are experiencing a type of meditative experience.
As a young child I experience this many times. They last only for few seconds. I thought that I was going mad and complained to my mother.
My niece also experienced the same and they take her to the doctors and the doctors said that there is nothing wrong with her.
I remember Mrs. Robert Holmes A Court talking about the same experience when she lost her husband Mr.H.A.Court (once Australia's richest man).
Sports people such as Tiger Wood also may have some level of onepointedness.
Onepointedness is a universal mental faculty and we all possess it that is why we all can realise Nirvana.
I know about this only now, as I have studied it and have a better undestandigng of it.
Meditation was there before Buddha’s time.

I may be wrong, if please correct me.
PS: As a child I was very much in to Buddha's teaching.
