Hello all

i'm man 30s with mental disability. I had some accident at childhood. car accident.
I've had bad nightmares ever since my childhood. I"m a senstive person and scared of many things including social.

So yeah, anyways? Why do i have many nightmares.
And interesteingly, although i can never get lucid in good fun dreams, i always get lucid in Nightmares...
well, im not sure if it's lucid...maybe it's not.
but i mean They are very vivid. Yeah that's what it is. they're vivid. But not lucid.

but seems always those nightmares are vivid and it feels like it's really happening. But other dreams, are never much like that.
Why?
