does it matter?
i think i’m an average sleeper =P
I guess it doesn’t matter that much, since it is only about what happens after you got asleep, that is quite irrelevant, unlike the way you fall asleep. Maybe being a lighter sleeper can bring more frustration for interrupted dreams, and on the other side, more WBTB/DEILD opportunities.
Besides, does a proper classification even exists? In my example, cannon fire won’t wake me up 
but I do react strongly to light.
i’d guess light sleepers have more lucid dreams, because deep sleepers are less concious during their dreams and therefore have a smaller chance of becoming lucid, but tosxyChor’s comment is valid that light sleepers may wake up from lucid dreams faster
That’s true but it depends on sounds.
If it’s quiet, you should have no problems.
I’m like Tosxy.
I’m a very deep sleeper, nothing can wake me up.
Sometimes in the morning people ask me did I fall sleep because of the thunder, they couldn’t fall asleep, it was very loud…and I’m like ‘‘What thunder?’’
I don’t know about deep sleeping, tho WILD should work better if you are a light sleeper.
The middle is always the best.It doesn’t even matter that much.Enjoy!
Almost anything can wake me up. So be quiet!! 
i can apparently “wake up” from my parents coming into my room, and have an intelligible conversation with them, while not remembering it happening when i wake up in the morning, but i never sleepwalk
