I have an unusually deep sleep. When I sleep it's really hard to wake me up. Sometimes when there's a heavy storm at night it wakes up my parents and all my sisters, but I never wake up. Yesterday night the siren in our little villages went off because a house burnt down. It could even be heard in the neighboring villages and again everybody woke up, except me. I kept sleeping.

Now, my question: can an unusually deep sleep be hindering to lucid dreaming? Make it more difficult, maybe?

Btw, I had one LD so far.
