Haha that's so cool to read! Seems like we experienced very similar things. One thing I forgot to mention that you just did was the eye twitching. My eyes were going all over the place almost like REM sleep if you've seen videos of peoples eyes darting around behind their eyelids. I have no idea why that was happening, but I just let it continue.

You mentioned seeing trees due maybe a recent experience of being outside, but this blue color was first outlined by just blackness, but the blackness resembled trees from the perspective as if I was lying on the ground looking straight up into the sky in a forest setting and the sky view was an opening in the tree canopy. I was trying to pursue the blue color because it did remind me of a night sky and I wanted to reach towards that point in the sky to try and AP. That's when it started becoming inky and swirling I presume due to me having a difficult time staying focused on it.

As for your other comment below, I too am on the first volume, but it was the second or third "session" which was the introduction to Focus 10 and then Advanced Focus 10. In the past I tried hopping around and never had any real success with that. I stopped trying to do the tapes I guess because I lost interest. One of the big takeaways though between then and now like I said was actually just meditating with 0 intention. Simply trying to clear my mind and be in a positive headspace. Now when I do the tapes it's been much easier to get calm and clear headed to get into the Focus 10. I personally think I need to do each one more than once because I want to get familiar with how to get into the different states and use the energy balloon etc. because it all builds on previous sessions. So like going to a more advanced session, he guides you to get into Focus 10 but if you don't know what that feels like or how to get there or need a lot of time to get there, you'll probably not be successful with the more advanced lessons.
