Lucidty Checks Used As a Nightmare

I have been doing lucidity checks for the past couple days. Last night I saw a very gory film that carried over into my dreams. My dream used lucidty checks to show me that I wasnt dream and I couldnt escape what was happening. I saw that words werent the same when I looked at them twice and I saw my hands had bubbles on them, but I didnt relize I was dreaming. Does anyone have any thoughts?
