I share this from personal progress I've made in a similar regard.
For me, I am not really that scared of DMT and hyperspace. You get me with the right people, and things are golden and I am going for it.
However, what's telling is how this stance completely disappears when I am alone. I don't like that. This indicates that it's not so much DMT and hyperspace I struggle with but instead aspects and dealings with myself that DMT is able to highlight. To be direct, having been delayed in ways that curtailed autonomy and sovereignty, there's a deep part of me, in my subconscious and nervous system, that still feels the need for permission. Because I am a grown ass man and don't need permission, yet never learned what it feels like subconsciously and in my nervous system to comfortably act on my autonomy, there is tremendous fear.
One love
