hello, welcome!
those experiences don’t sound like fun indeed (to put it lightly)
my first thought is that you could use your LD’s to face those fears, / conquer them somehow (there are strategies for this). So not let it hold you back from LDing, rather tell yourself before going to sleep something like - if I know i’m dreaming and that happens again, next time i will - (and then visualise the thing you want to do to defeat it).
edit: also you may want to read this topic for similar experiences (sleep paralysis/night terrors)
