Do you feel refreshed when you wake up? If so you are very lucky... galling to sleep instantly is very rare but very useful! People who lie awake thinking when they’re trying to sleep think of worry’s about the day ahead, often leading to less sleep.
As for the unconscious thing no... you are conscious at all times, and when you are asleep you are conscious, but in a different state. There are five stages of sleep, 1 and 2 is when your brain starts to slow down, but you can easily be woken, 3 and 4 is the deep sleep which is almost like an unconscious state as it is very difficult or impossible to wake someone, and stage 5 or REM sleep, which is when the brains activity starts to increase, which is when dreaming occurs... if you find that you sleep soundlessly without being awoke, then you must fall into a stage 3 or 4 sleep very quickly... so that’s quite good in my opinion!
