It's funny because usually when I'm about to go to sleep, I'm doing something on my phone or iPad and the next thing I know I'm knocked out. I wake up not even remembering that I fell asleep. Makes sense now!

Did you know that sleep is a form of unconsciousness? Some people may be afraid of fainting, but the reality is, everyone is (almost) unconscious every day in their life. Does it sound just normal to you? Do you make a difference between sleeping and seeing someone who is unconscious? You are unconscious when you sleep.
a condition of body and mind which typically recurs for several hours every night, in which the nervous system is inactive, the eyes closed, the postural muscles relaxed, and consciousness practically suspended.
Never googled this, Honest

i have some REM sleep behavior disorder.. pretty weird tbh. couple months back i woke up standing a couple feet from my bed. turned on the light and there was blood all over the floor. had cut my foot open pretty bad couldnt walk on it at all for a week.. actually made me scared of sleeping for a few days
I've got a bit of a messed-up sleep pattern due to a number of years of my husband doing shift work, often nights and other horrid rotas.
I always sleep in two chunks; one during the day of about 2 hours and the other from about 3am to about 8am. I never remember my dreams from the longer sleep cycle but nearly always do from my short one.
I wonder if I'm 'unconscious' for one and not the other. Or not at all.
In Winter I goto bed around 8-9pm. Read a book for a few hours then sleep. I might sleep for 2-3 hours then wake up as though I've had a good 8 hour sleep lol.
Within an hour I'm tired again and try and get my second sleep. It sometimes works. Then I get up anywhere from 5-6am till as last as 10-11am.
If my dog sleeps in so can I. If not then were both up and then get the parrots up. They hate me getting up too soon and start screaming. They really need a good 8 hours sleep and with my messed up sleeping patten they sometimes don't get it.

Up until around the 18th century, the norm was to sleep in two phases - a "first sleep" that began shortly after dusk when the day's work was completed, followed by a period of wakefulness and a "second sleep" that continued until dawn.
I can't say why that changed. If I had to guess ... industrialization began to transform lives with more structured time periods or "shifts" so that people broke the day into three time segments - Work Time, Home Time, and Sleep Time.
So I think your body is simply responding to nature, wanting to sleep in phases. It's pretty common for people to "have a little nap" in the evening, especially after a meal. I hear people talking about it all the time, how they sat down to read or watch a movie and dozed off for a while.
... On Topic ....
I remember 15 or 20 years ago there was a Usenet group specifically for discussing the nature of consciousness. It included researchers from Stanford, Johns Hopkins, Cambridge, Oxford, MIT, CalTech, and others I don't recall. Also included many robotics and software researchers interested in AI consciousness.
At the time, there was no consensus among experts on what actually constituted consciousness or what gives rise to it. Where are the lines drawn? At what point do brain & sensory processes conflate into consciousness? Is there, truly, any such thing as unconsciousness?
Many provided research and anecdotal accounts of patients who formed memories and even learned things while under anesthesia, during surgery for instance. (A time when they were certainly "unconscious" by any objective measure.) All quite interesting, highly complex, and often esoteric.
I think consciousness isn't really a Yes/No, On/Off situation. More a flowing from one state into another, and back again.
