Credible Discreet Paranormal Investigator Wanted

I apologize for abusing your forum in advance (seems like a nice place) that said if this post does not meet your standards please delete.
That said I have what I perceive to be a persisting entity affecting me at night, in a negative manner. I consider myself to be a rational person, my story seems to follow a logical series of events and I would like some answers and to mine the experience for what evidence it may present to science. It is consistent though definitely related to my state of mind and it seems totally possible that if the correct instrumentation were used it would validate the occurrence or at worst point to some more logical rationale. Like the title said if anyone is aware of someone who may have the equipment aptitude and desire to look into this, let me know. It no longer registers a great deal of fear for me, as it has persisted off and on for so many years. Let me know my email is [email protected] and I live in Connecticut.
