Fear of heights

I have a fear of heights and in a LD I cannot fly above or jump over about 20 feet. Is this easy to overcome?

I used to have your problem, as I was afraid of heights as well. With practice, and telling yourself that nothing can harm you in dreams, it sure can be overcome. Approach your goal with a relaxed mind, and it can be easier. Just take it one step at a time. I got less scared of heights in lucid dreams by jumping off tall buildings, and then landing.

Not sure how easy it will be for you, but if you try and do overcome your fear of heights in your lucid dreams, you might find yourself being less afraid of heights in real life. That's what happened to me. :)

I'd say yes. Just say to yourself that nothing bad is going to happen to you. I know it easier said than done, but sometimes you can limit yourself in dreams. Once you realize that there's nothing to fear in a dream, tons of doors will be opened.

EDIT: Darn you Lumi, you beat me to it!!!

I would say just after you do some RCs and figure out its a dream you must convince yourself that you will not hurt your self but i still wouldnt jump off of anything simply because in case you werent dreaming then well it would just suck i would say try to hover first then if you do you could try jumping off of a building:)
