Tell me about your Imaginary Friend(s)?

So I've always been low key on this. I've heard of Tulpas, but I find them problematic in well a lot of ways. But I've always been super interested in imaginary friends and invisible companions. I my self have had my own. But all the ones I've had in my childhood couldn't hold a cake to my first one.

I just sort of called them my Voice. They were super nice, had more maturity then myself, and never really took a form. I never really tried to make them. But they'd always encourage me and were super interested in the world around me. Like fascinated by like everything. They loved watching bugs and just sort of guessing at how the world worked.

It all came to head when watched some movie at my church and it was about this puppet family. One of the sons heard the voice of Satan. It had worried me kind of scared, cause well I hadent thought about this Voice a whole lot. But I sat there and thought really hard about it. They didn't tell me to smoke cigarettes and do bad things, so Satan was ruled out. And they didn't speak like they were G man in the sky with some all knowingness to them. So I thought "Their coming from my imagination." this meant that they were coming from inside of myself, I had this sort of washing of positive emotions over myself from that realization.

I eventually grew out of it. Little me just used imagination for things like art or writing or other things. But I've never really heard about how children experience imaginary companions. Cause usually children always know their not real. But it still doesn't mean they aren't experiencing something. One of my last interactions with them was seeing something that was profoundly wrong. I don't remember what but they said. "Something's really wrong with your world." That was some of their last words to me.

So any of you high strangness folk have encounters or any experiences of things you could only say could come from yourself?
