My inner voice is my voice as I hear it, and is more obviously there when I’m contemplative or reflective on ideas and concepts, but it doesn’t seem to actively dictate or narrate most of my actions as I go through the day, except perhaps in anxiety or adrenaline peaking situations. It does seem more likely to flip to the forefront when there’s an ‘emergency’ sort of moment to help stay calm and rational where others may panic. I do have some ‘imagery’ thoughts but only when I’m on more of an autopilot with an activity.
Interestingly, I can have very vivid and detailed dreams filled with unique imagery and events that can seem very real and my inner voice kicks on sometimes during dreams, and I recognize it as a dream. I have at times been able to influence the direction of a dream that my subconscious usually seems to be running. These dreams can be expansive, I’m talking deep backstory, knowing things and languages I do not know, knowing details about history or science or math that I do not know, and having a strange hyper awareness of existence around me that I do not have when awake. The only really ‘scary’ dreams I’ve had since I was a kid are ones where I can’t find my kids, or where my dad is still alive and shows back up at home like he was just living somewhere else for a while (and it’s not so much scary as just hyper-confusing and stressful). The dad dreams are also some of the best dreams to have that inner voice of awareness happen.
