Inner voice. Does he exist?

Good afternoon friends!
In the life of each of us sometimes mysterious things happen and no one can guess this riddle.
Someone connects this with God, someone even considers it to be devilry, but still a large half of humanity speaks of the inner voice of a person.
Inner voice - what is it and does it really exist?
This is a very interesting question and the answer to it can be a large number, since each person will interpret it in his own way.
My late grandmother always told me to listen to my inner voice. But somehow in my life I mainly relied on my mind and strength, but what sometimes so agitated my soul and a double impression appeared, I cared very little.
It happened about three years ago when I was in the hospital. Then I had a very difficult period, I almost had to live in a hospital ward so as not to suffocate from tracheal stenosis.
Every two weeks I was allowed to go home to take a good shower and bath, as well as to collect a new change of clothes. And this time, while packing my bag, I took two pairs of slippers.
As soon as I put them in my bag, some voice from inside me asked for what purpose I needed two pairs of slippers, besides, one of which was very uncomfortable and with slippery soles.
I did not attach any importance to this, packed my bag and left for the hospital.
The next day, I had to go to the endoscopy room for an appointment and decided to put on those uncomfortable slippers that my inner voice kept telling me about at home.
You will think that I have lost my mind and carry various nonsense, but again I heard this voice, which advised me to put on other slippers.
I hesitated for a long time, trying to understand if I was going crazy, but still did not listen, put on the ill-fated slippers and left the room.
When I went out into the lobby of the clinic, the question arose - to go from the fourth floor to the second by the elevator or walk up the stairs.
And he, this vile voice again, again advises me to take the elevator, and again I do not listen to the advice and head for the stairs.
I went up the stairs to the third floor, and when there were a few steps left to the fourth, I was already unconscious.
In my head there was a noise and a mixture of female and male voices, which vied with each other asking what happened to me, who I was and from which department.
I opened my eyes and looked at my posture, in which I was still unconscious - my left hand held tightly to the railing, my right hand, bent into a fist, rested against the concrete stairs, and my fifth point was in limbo.
Gradually, I came to my senses and then my doctor appeared next to me. As if by a wave of a magic wand, a wheelchair appeared and I was first taken to the endoscopist, and then for an x-ray.
It can be seen somewhere along the way I was injected with painkillers, because I didn’t think much.
Then I was taken to the ward and after 30 minutes they took me to the traumatology clinic to make the bones of my right hand and apply a cast.
It was the first turning point in my life, but the experience is certainly not pleasant.
The arm in the hand was swollen, it was twisting and breaking all over and I just had to deal with intolerable pain, because after the dose of hormones that were poured into me, no painkillers helped.
Of course, I analyzed the situation for a long time with a voice that suddenly appeared on the subconscious, which wanted to guide my actions, but decided to do everything in my own way.
It happened again. This voice again climbed into my head and began to repeat that I should protect my loved ones from cutting objects.
Brad, Brad, Brad….

This cannot be and this cannot be believed - it was spinning in my head and I could not figure out what to do?
After a while, everything calmed down. A week passed and my husband took me home from the hospital.
Already on the road, the son's wife called us and said that he had injured his left hand. The son was making a cement mixture and the gears of the concrete mixer grabbed the glove on his hand and scrolled it among themselves, thereby crushing all the fingers.
A few days later, my husband cut his finger very badly.
I did not believe the warnings of the inner voice and this is what happened.
Usually people say that it is our guardian angels who are trying to protect us from misfortunes, but we simply do not believe them and trouble happens to us.
And now, convinced by my bitter experience, I now try to listen to the voice of my angel, but for some reason he has been silent for several years.
