Completely unaware I'm in a manic episode until it's too late

I remember one episode in particular that I still regret and feel guilt and shame about to this day where I was doing completely out of character things with high energy and no need to sleep only to find out months later it was a manic episode. The episode lasted a month then I fell into a depressive state after it ended and then continued on living without the realisation or diagnosis at the time that it was a bipolar manic episode. I went on to have a few more and again without my realisation, I even had one during my stay at a mental hospital.

Does anyone have the same experience where every episode we've had we've never been able to recognise we're in one? I guess this also proves to me that consent doesn't exist in mania as we don't even realise or can control it.
