These sounds would overlap, repeat, and cycle again and again for up to several hours at a time. It always happened in the wee hours of the morning, between midnight and 5 AM generally. 4:30 AM PST seemed to be the most common time during which this would start to be heard.
This has gone on for YEARS now, until very recently, regardless of where we lived or what phones we were on. After a particular instance recently - which I would prefer not to detail because it's just too bizarre, and frankly I already expect half of you to think we're just crazy or pulling your leg lol (I assure you, we're not) - all of this activity ceased. After years of it happening almost every night, usually around 4:30 AM PST. It hasn't recurred since
So, I just have to ask...why are you and your friend on the phone nightly at 4:30 AM?
