It's not anything to be scared of. You can't be "traumatized" by your own lucid dreams because YOU are in full control (somewhat). Unless your own daydreams scare the s*** out of you, you should be fine. You're more likely to have a scary experience dreaming normally (nightmare), which by the way is completely created by your own emotional reactions. Lucid dreaming is a lot more fun than scary, and every dream you've had was a lucid dream it's just you weren't aware that you were the architect. It's a very personal, individual experience which is completely up to you.

The only thing that will truly scare you is sleep paralysis if you manage to induce it consciously.
