On the corner of Copacabana beach. I experienced the same sequence of events — same couple walking past, same seagull, same cloud formation — six times before it stopped. My phone timestamps show a single continuous recording.
I boarded at 19:00 and the next thing I remember is 22:00. My watch had stopped. Three other passengers experienced the same gap. None of us had slept.
For those who followed my post from March: the infrasound events have started again. Last night at 1:40 AM the same deep rhythmic pulsing began — felt more in the chest than heard through the ears. Our dog refused to go outside. My partner, who was previously sceptical, came and stood next to me on the porch and didn't say a word for ten minutes. The frequency seems lower than before. I have borrowed a calibrated audio recorder from a friend who works in acoustic engineering and I am going out at midnight tonight to get a clean reading. Will post results tomorrow. If anyone in the rural Cascades area has experienced similar in the past week please comment below — I want to know if this is localised.
