"Bad Vibes" in a LD.

I had a lucid dream the other night in which I actually got incredibly nervous/creeped out for the first time.

"I woke up in my bed back home. I was already thinking I was dreaming, but for some reason had to struggle for lucidity. As soon as I did, I leapt out of bed and ran down the hill outside my house and found a gate leading underground.

I entered and followed an underground passage way, went through two or three gate/fence doors and came to an opening in the cave-walls. There was a large, ornate door on the other end, and as I approached I got very nervous. By the time I was at the door, I was getting what I can only refer to as bad vibes. I left immediately..."

Usually in my LDs I'm never worried about anything, or scared by anything. I always know that Its just a dream and I'm in control. However, that did nothing for the fear I was getting from that door. I'm incredibly curious as to what was in there...
