Guardian angel

It's not the first time
You appear in my dreams
You were always in white
Always holding my hand
Always reassuring me
Everything is alright I am by your side
You appear recently
While I was jumping through several hurdles
Like a martial arts expert
When I came to a real high wall
Everyone jumped down effortlessly
I was afraid of the height
You suddenly appear at the opposite block held out your hand and lower me down
What are you? Who are you?
Always smiling yet never a word you said
Whatever it is...
I believe you are always with me..
In my happy times
In my struggling times
In my depressive times
Thank you
Thank you my Guardian Angel.
