Hello and hope you are doing well.
In the initial phases of the sleep cycle and while awakening, we tend to be more conscious or alert. If we study the brain waves at these phases they tend to show the alert wave pattern, this could cause the awareness. If it is not interfering with your sleep schedules you don't have to worry. If it persists or is troublesome consult your doctor for assessment.
Hope this helped and do keep us posted.
it definitely sounds like sleep paralysis i've had this for years....don't worry there is help and you will start to control it but you have to know what to do....no, you do NOT need Doctors and no you do NOT need any meds...and no you are NOT crazy...there are many people who experience this just like you.
Please visit my youtube channgel: InsaniTeesintl or LeoniEwithanE - see my playlist either: 11:11awakening or Conspiracies its in one of those you will find vids called lucid dreams, and so much more on the dream state and how to control it.
email me there if you need any more help but listen when I tell you I WAS JUST LIKE YOU but now my sleep paralysis are becoming less & less and I'm constantly winning - you can do this...take control of your dreams...remember, we control the dream world and you will win!
Until next time

No idea, happens to me alot, but it is right at that threshold where you can lucid dream, give it a try, you can do or be anything you want. :)
