Hello,

I don't think I have ever had a lucid dream in my life. Lately, I have heard people on the internet talk about lucid dreaming. Well I want to try it since it sounds cool.
So I found this site and the info on the homepage is extensive but a bit confusing.

There are some things that are puzzling (and scaring) me.

1) False Awakenings - I have read about how people can think like they are waking up but they are still on a dream. Well, I am scared because i think that might actually awake and think that its a false awakening and do some stupid stuff. I dont want that to happen.
Are false awakenings always obvious?

2) Reality checks - What exactly is a reality check and how do I do it?

3) Lucid Nightmares - OK I am scared of this one. How often do people have lucid nightmares? Do you know whether you are still dreaming or not when having a lucid nightmare?
If it matters, I don't frequently have nightmares (once a month usually).

4) General precautions - Are there any general precautions I should take before I try to induce a lucid dream? Is there any danger in lucid dreaming? Brain-damage? Physical damage? Does your physical body move when lucid dreaming? Does lucid dreaming help sleep-walking (which I don't want to do)?
In one sentence, what is the catch?

Thats all the questions I have for now.

Thanks in advance.
