Awwww, what a nice avatar! You look familiar.

Anyway.. I can totally relate with that utter panic that you felt. A lot of my FAs are pretty freaky.. nothing really happens in them, but I feel a presence or something unnerving in the air.

Of course it's all in your head though. Did your last two LDs go normally? Like Death-Wuad said, just think pleasant thoughts. Reason with yourself, say something like, "Hey, that experience only happened once.. I'm moving on now. It's just my imagination, and from now on I'm going to imagine better things."

Ooh, also what I've noticed.. if I have a LD or FA when it's light outside in the real world, it'll be bright and happy in the dream world for me. It's when it's dark out that I have frightening experiences sometimes.
