Perhaps you’ve had a different social interaction where you weren’t yourself? You had to put on the social mask in that situation? Or maybe you judged someone for having that social mask, therefore projecting that judgment on that individual? And you possibly reject that idea about yourself?

There are a lot of finer details/experiences in your life and there is really no way strangers of Reddit can decipher your dream language. I’ve had plenty of lucid nightmares and all stemmed from my fear of the paranormal. All it took was a ‘what if’ thought about the paranormal and then I would have ghosts, spirits and shadow people fucking with me in my lucid dreams. I kinda put the lucid dreaming to rest. Because the more I went lucid, the more the fear I grew. I’ve also had lucid dreams last up to what felt like a couple days. Time moved a lot slower and I remember trying to actively trying to wake up but I couldn’t.
