For the past few years I've been dreaming that I'm choking on gum a lot and one time it got so bad that I was standing over a trash can gagging trying to spit it out, cotton balls, rings, movie tickets, & once a rat which was terrifying. I wake up and can feel it in my throat and I keep choking, gagging and trying to get it out of my throat. Eventually I'll realize I'm fine and the sensation will go away. There's been a drew times where I've fallen asleep for a few minutes and woken up to feeling like there's a lump/object in my throat. Could this all be due to anxiety?
