destiny

about destiny....
I would like to know your thoughts about this fascinating topic/
First, I will tell you about two moments in my life when my destiny, or at least, part of it, was "told" to me.
The first time was when I was 14, in the daytime, everything disappeared and I found myself under a vast sky, clouded, but beautiful. I was extatic, overwhelmed by the beauty I saw, it was like a vision if heaven. Then I KNEW (the knowledge sort of came to me), that my life would be difficult, but that there would always be this light at the end (not necessarily of my life....).
Then, aged 28, in the daytime too, I sort of imagined seeing a girl jumping in the grass and thinking "I wish I could jump like that". It made absolutely no sense to me, untill I was diagnosed with ms and really had those thoughts very often.
Now, it is difficult for me to walk freely, but know will overcome this, I am convinced.
I could go on, but let us see if there is any response on this. My question is, of course, what is the degree of freedom given the assumption that destiny exists, although it is quite general and rough...
thanks
