What happened, which part of it did you dream about?

Does that mean anything to you, or was it more just images from the TV that you've seen loads of times?

So then were you afraid, how did it make you feel? Did you have similar feelings in the dream?

I didn't dream about it; if you dreamt about it as you say and want to understand what dreaming about 9/11 means, then you have to know how it makes you feel in waking life - it means different things to different people depending on how they feel about it.
