1) Did you see an otologist (ear doctor) about a possible approach of signs of deafness?
2) Did you consult an ophthalmologist (eye doctor) about possibly having a grey or green star (eye illness)?
That's the kind of answers you're asking for here I guess, not exactly the right forum for such.
Seriously though, you've got some paranormal symptoms around you there. Any chance you could describe the contents of the nightmare(s)?
