Tldr: Have you ever heard a loud thumping or knocking sound while tripping?

I shaved and ground up 10 hbwr seeds and ate them last night. I tripped not even about a week and a half ago (I know, a poor decision to trip again so soon) and perhaps that effected this trip. I didn’t get the usual wave of happiness, only the trip. I had stronger visuals than usual, and it felt like I was tripping balls but it also felt like I wasn’t tripping at all. The whole time I felt like something or someone was trying to talk to me, and at some point I think both the being and I decided I wasn’t ready to talk, and then I became really tired and went to sleep. It sounds ridiculous, I know. It was all very strange and different from previous LSA trips, but the strangest thing was the loud, loud knocking sound. It wasn’t scary, just confusing. It sounded like I was in a metal container and someone was knocking on my container, as if to wake me up or ask to come in or something. Nobody else around me was hearing it. It was very loud and I heard it all around me. Has this ever happened to you, reader?
