what if, in your dream, you are in a life and death situation.
I was getting robbed last night, and it was very realistic. I didn’t have time to do a RC b/c I didn’t want to get caught hiding from the robbers, if it was a real.
What can you do to realize that you are dreaming?
I’m assuming you’re not talking about how would you know if you’re actually awake or not when you’re getting robbed, but how to become lucid from a situation like that.
I’m sorry i doubt i could speak for you when i say this, but usually in a “Life or Death” situation in a dream, i will somehow instinctively know it’s a dream whether or not i become lucid or not. So i could be chased by some baddies on the roof of a building, and say to myself “the only way to escape is to fling yourself off the roof and FLY AWAY.” I won’t even be lucid at this point but i’ll somehow know.
So sometimes if you haven’t got a chance to be lucid, you’ll probably still act as though it was a dream anyway, and maybe if you can become step back and understand that dream thought pattern it could help you realise you’re dreaming.
Hopefully that helps 
While I was hiding, I thought I might be dreaming, but I didn’t want to move at all, since i thought they would hear, or see me.
what about nose blocking and hand checking?
they dont require much movement
ya, but I was hiding behind a chair, I didn’t want my head to move. And I didn’t want to make a noise when I did a nose check.
i say u just do a reality check and get over it. I mean like c’mon its a dream nothing can happen to you!!! 
Well, if someone is running around your house with a gun, I think the last thing on your mind is lucid dreaming. Well at least for me.
well, try and make sense of the situation then. if you find you cant, chances are your dreaming
haha, thats great. 
No, i don’t think i would be thinking that either
Perhaps you could try an RC that doesn’t require you to move.
Such as closing one eye and looking at your nose?
If you can’t see your nose you are dreaming. I doubt the bad guys would catch you for closing one eye
If you still aren’t sure then maybe that RC would give you a little more confidence to try your RC of choice
ok… that’s a pretty good suggestion, but for now on, even if something barely change in my everyday regular day, I will do a RC.
