I was googlin' around for answers, but I didn't find anything like this. So I figured this forum was the place to ask.

I have managed a few times to become lucid by telling myself "this is not real" before I fall asleep. But I keep hitting this brick wall when I'm actually in the dream.
I experience the most intense fear, chaos, loud noises, hallucinations, and general terribleness. Causing me to become completely paralyzed, just watching this for minutes before waking up.
There is nothing in particular that makes me afraid, and I'm not an easily scared person. This is just completely bonkers.

Have any of you had this problem? In any case, I'm looking for an explanation. I get some frightful thoughts when I wake up after that.
