Hi Milamber !
Welcome to the forum !
To me it seems like quite intense, to have this experience every night.
It is considered normal to have this experience at least once in their lifetime, but since you seem to have had this since childhood, I can't help but wonder if there isn't some condition that is the cause of this ?
It is possible for people with your condition to ask a doctor to examine you. I checked some information on the internet, and it could be that ( for instance ) you suffer from a distinct form of narcolepsy.
Not everybody experiences it the same way, yes, some suddenly fall asleep in the daytime, but others have symptoms that could easily be described as insomnia, while in fact it could be nacolepsy.
But it could also be something entirely else, I am no doctor.
That is why I recommend you visit one.
