Time that it takes to achieve first lucid dream varies alot from person to person, for me personally it took like a week, some people can get it on the first try while others need alot more time, think positive and keep practicing!
I suggest checking this thread about some good information on DILD: http://www.dreamviews.com/dild-gab/1...ods-dilds.html
As for WILD, there's nothing to be scared about, hallucinations can't harm and they even can be controlled, don't think about scary things and they don"t happen, and even if happen think about good things. But they are not aim of WILD, for WILD you just need to fall asleep while keeping awareness, check out those tutorials if you want to try it:

WILD
Also check out this thread for more info on entry types: http://www.dreamviews.com/wake-initi...ntry-wild.html
Whether to choose WILD or DILD is up to you, it varies from person to person which one works better, i personally use both methods since for me they work well together.
