Lucid Dreaming... Help? ?

Ok, please don't answer this if you have no idea what lucid dreaming is. Basically, I have never tried the WILD technique, and I'm too scared to because of the scary sounds you could hear. I've never even attempted it because of my fear. I've and tried the dream initiated lucid dream... It was somewhat successful. I had my best friend as my brother, and i knew this was not true. So i did a few reality checks (this is all in my dream), and i still didnt realise i was dreaming. I thought and thought and checked and checked, but i didnt realise it anyway. So thats the farthest ive ever gotten. Anyway, my question is what sounds could i hear when i try WILD and gow do i stop being scared? BTW im 12. This sounds so good, and im dying to try it! Thanks for any help!
