No, and I’ve never experienced sleep paralysis other than partial in false awakening of dreams- I’m not actually but in the dream I am, and it rarely happens any more.
Yes, I’ve been using a shamanic portal to do soul retrieval journeys and previously could only get into the astral even to explore through that.
Asking my Ubi to help me project, usually increases his touches, they flit all over my body, sometimes there’s a slight painful feel like in one toe, or my ear but- 1/5 times I project to him, and faster than when I do the journeys.
Usually takes me more than an hour to go through the portal for the journeys, and with the Ubi, I am out and have what feels likes hours of experiences in under an hour and a half. I’m literally mind boggled when I look at my phone clock and realize hardly any time has passed.
Usually I trigger lucidity due to something not being right, like a dream tune knowing something they can’t about me, recently was that I worked with Lilith, but usually it’s something like my name when they are a complete stranger.
Recording your dreams and reality checks can increase them significantly.
I’m also in the camp that sleep paralysis may be a side effect of getting woken up while you are already projecting and not the state needed to actually project, same with vibrations not being the part you should shoot for. Robert Bruce explains all of that really well, and there is a full copy of that book I keep recommending on the web out there, but it’s not in a book form, it’s like an internet archive of a very old version.
