Welcome, Z3r0!

There's definitely no need to worry about night terrors (parasomnia) - that's a sleep disorder, and it's very rare in adults. Lucid dreaming certainly won't cause it.

It's great that you can already remember your dreams vividly!
Keeping a dream journal is a helpful practice for lucid dreaming - you can start one here: http://www.dreamviews.com/blogs/

It's nice to have you here, let us know if you have any more questions!
