Sounds like you are overworked and underslept, and that the sensory deprivation that you experience while in that dark projection booth for hours on end is playing tricks on your mind a wee bit. Not that this will explain away the technical difficulties with the equipment, but it certainly isn't uncommon to be having odd sensory experiences given the pairing of "sensory deprivation and lack of sleep." Your alcohol consumption may also be magnifying this mix.
"taking a little time off"" seems to be in order, and exploring other employment avenues may also be a good idea for you.

As to your recent promiscuity, be sure to use protection EACH and EVERY time.
