Well lately I've been getting more lucid dreams than usual, though they all end as soon as I realize I'm dreaming.

Anyway, last night I became aware that I was dreaming. I went to perform a reality check and I pinched my nose and tried to breathe in... and I couldn't! So I'm like "why can't I breathe in?" because I knew I was dreaming. So I close one eye and look at my nose and its there. So then I try a few more reality checks like pinching myself but none of them worked.

Then I try to run through my friend so I run into him and I fall down.

You might be saying "well why reality check if you knew you were dreaming?" but the thing is I wasn't even sure because it was so real

I've only had such a vivid lucid dream a few times, even though I ended up not doing anything.

Quite perplexing.
