First of all, Hello to everyone, this is my first post

I had my first lucid dream the other day, it was short and not compleatly clear. Well, i recognized it by the "fingers through my hand" technique and even managed to summon a person in front of me. Then i felt that my lucidness is fading and i continued to dream a regular dream. Well... its a common story for beginners, but i noticed that while i was lucid dreaming i heard no sound at all. Like on the "mute" mode. Is it normal for the newbie-dreamers not to hear sound... maybe the willpower isnt strong enough or something? I have been trying to LD for about a month now, im writing my dream journal and doing RC's (not very often, but still).

Help me out on this one
