That’s OK! It’s what you’re brain does! It wanders, and that’s normal. There’s a technique called “labeling” that helps get you centered when you wander. Simply notice that you have moved to thinking about something else and label it “thinking” and re-center your focus. You’ll notice after you practice this for a while you’ll be able to focus on stillness longer than you had before
having ADHD, my monkey mind is constantly running, but this was helpful
I got sad 
Its running the same loops
Dozed off
I wrapped my mind in a membrane and floated on the outside. I‘m pretty sure if I’d let myself I could have floated there and fallen into the bast if sleeps. I pretended I could reach through the membrane and grip negative thoughts and crush them, almost like one would at a cellular level.
It was definitely helpful to imagine myself as an observer of my thoughts rather than being my thoughts
I don’t know how I’m supposed to observe my mind while I’m using my mind… Don’t use your mind, just observe it makes no sense when I have to use it to observe it. I cannot observe it from within.
I observed there was a slow shift from the busy thoughts about my day or the near past and future to a form of inner talk where I was sort of describing my thoughts to myself, and finally to a sequence of images and feelings similar to dreaming, by connection of thoughts
My monkey mind started off a bit chaotic and then it slowly become more like a lazy river
I still felt quite tense physically while working on this exercise. At the same time my thoughts quickly drifted to the sexual.
