[At this point, Javik didn't have it in him to be annoyed that someone looked human, but claimed otherwise. Most of them weren't telepaths, though.]

You will need to be more specific. Exposed to what?

If they are not yours, then find a way to remove them. My people could do this - store memories to preserve them, or be rid of them. If, because of your telepathy, these nightmares are from an outside source... then I do not know the solution.
