i sort of recently got back into lucid dreaming
Dreams almost always resolve themselves. If this is a recent problem, I would give it a few months. Allow yourself to relax into your practice and not be too concerned about particulars of this dream or that dream. Lucidity is most important, and after that, relaxing and being there. You will have the most fun this way. More things will spontaneously happen. The dream will surprise you in different ways.

Second of all, it's OK to be afraid of the experience, but you should see that the experience itself is not fearful. There is someone there (you) thinking, "This is scary! It's frightening to be in something so real!" or alternatively, "It's scary that it isn't very real! I don't like my static body!" Just recognize that fear (and the thoughts) as part of the dream and then breathe deep. It's OK to feel fear and if there is acceptance the fear will resolve itself.
