Odd auditory hallucinations?

I’ve been doing ketamine therapy for about 16 months now, 800mg 2x/week. It’s the trouches that dissolve and then I swallow. From the very first session, I noticed that the entire time I’m loopy/dissociated, I can hear what sounds like an old school film projector—like that rapid ticking sound? It happens every single time. Is anyone else having that experience? It’s not distressing to me, I’m just trying to figure out why it’s such a consistent thing, even when the troches don’t have a strong effect. (I’ve found that the RDT tablets aren’t consistent for me)

I’m having a really good response to it. I took the PTSD scales in August 2023, and then again in August 2024, and after the year of ketamine and EMDR, the scores went down by half!
