I often wonder if I actually did something or dreamed it or told someone something or dreamed that I did, or that someone told me something. It can be pretty confusing for sure. Sometimes someone will say something to me about something and I have a little realization that it did happen and wasn't my imagination.
In the past I just did not have enough awareness of my life to even think too much about when things like that happened. It was just a normal every day occurrence. As I became more aware of what was going on and what was normal, it was like a bucket of cold water in my face. It still throws me when I see it, but I just have to keep remembering what T says. I'm just becoming more aware. It's always happened, it's just that my awareness of it is increasing. And that's a good thing.
Hang in there. It will get better.
