Any advice on how to be less in my head about things. Most times I listen to audios and end up thinking along the lines of 'is it working' which then subsequently makes it not work as I am too aware of myself.
So first thing, you're not alone, a lot of subs struggle with a kind of hyper awareness, an intense focus on wether they are doing it right, wether the inductions working, wether they can sink, are they feeling it properly.
That kindness internalising is the BANE of hypno subs everywhere and it can occur to even practised subs from time to time. Truthfully, listening to random hypno audios is not the best way to experience a trance or to achieve that state.
This is assuming you legitimately want to experience trance either as a part of hypnotic submission, or even just self guided meditation. You need to be in a state of trust, you need to trust the person inducing you, wether that means listening to an audio over and over again untill you feel safe, or striking a conversation with the tist or domme that recorded it. You need to be able to calm yourself down, you need to trust what's happening to you, you won't be able to feel calm or safe otherwise.
Contrary to the popular CnC myth, you can not be put in a trance unwillingly, even covert inductions have their limits, so you need to be able to trust that what's happening to you is safe, character and preamble aside, yoy need to know the person your interacting with, wether conversationally or recorded, isn't going to hurt you, or your brain just won't switch off, so step 1 I encourage you to talk woth ant perspective tist or domme, or ask they're subs or fans of their work, you need to be able to feel calm.
Step 2, repetition, just listen and watch, try not to form an opinion and expect nothing, just relax, watch and listen, let the words and visuals do they're work, once you've established trust, once you feel safe, just sit back, relax, and listen, focus on what your watching and listening to, everything else is distraction, just watch, listen, focus and breathe, it might take once, twice, maybe ten times, Don't try to analyse, just relax and listen.
Step 3, sometimes it helps to watch a full video with some kind of visualisation, if you have an audio yoy want to try, out up a visualiser you find relaxing, something that draws and holds your attention, I know spirals are popular, but everyone's different, spirals, pendants, even a dancing flame, something that can hold your focus, whole you listen and relax.
Step 2. Repetition, Focus on watching and listening, no expectations
Step 3. Find a visualisation that will hold your attention
If all else fails, my DMs are always open
