Yup. I start REM within 4 mins, as my studies showed. Crazy! Sometimes I don't know what's real and what's a dream. That when it gets scary.

Thanks for your comments. Sometimes it is the same with me.

Well, that's not me. There are times when it seems like I start dreaming as soon as I close my eyes.

Yes and that is called idiopathic hypersomnia which means they can see on the MSLT that you fall asleep in under five minutes but then you have no immediate REM stage sleep and that is apparently the key marker for narcolepsy
