I think I had them when I was kid, but not anymore.

And just to be clear, I didn't mean that I fall asleep as soon I close my eyes. It's just that there is no "transition" between being conscious and sleeping. And then, suddenly, I'm awake.

I have that idea that my mind suppresses the memories of dreaming and falling asleep, because when I was a kid I had two recurring nightmares that I dreamed of almost every night. Still, never did proper research on this topic.

edit: typo

So if you try to stay awake like Dali you will only skip time intervals without seeing anything? That's interesting. If I am too sleepy but still awake I even start hearing sounds and start seeing vivid images in my head with open eyes.
