I almost send my mind to past... and I didn't planned to do it.
I tell you what I did.
I cried a lot. I felt loneliness and stuff... you know.
It was late in the night, I was on my bed. When I felt I had enough, I stopped.
Then I started to feel more clean and ok. After a while, random thoughts were passing by on my mind.
In one of them I was walking on a supermarket. I remember the sense of being there.
That was all. Immediatly I got excited because I thought that I could really do a quantum shift to that point, in the supermarket.
But me (my mind) started to think many things about this quantum jump and I couldnt continue that way.
I doubted how I was supposed to reappear standed up and walking if I was on the bed...
but you know, that doesn't matter. A long time ago I was trying the same, a quantum jump like I were a magician, just using my hands as a magic stick, and that day I fell asleep and I saw myself being a teenager again, playing in the same park a long time ago I was, the matter was that I woke up very fast and I was worried about this current dimension.
So I dont think age or location does matters, because it dosen't.
