UPDATE: Oh, I just realized this was a sit that happened a month ago. In that case, my main question is: what has happened since then? How are your sits now? The rest just confirms your assessment.
I was going to say, considering the sit started off in A&P, you saw clearly A&P->Dissolution, it was more intense than before, and you meditated for 2 hours without noticing it, maybe you had already gotten Stream Entry. Have you noticed anything in the previous month that supports that?

Andy R:
When the chime rang an hour later, I woke with very strong body bliss and intense pleasurable sensations building up. The bliss kept getting stronger and more pervasive, and finally peaked with a very strong body rush. Shortly after that peak, the intense bliss and pleasure rapidly faded, and I felt a lot of coolness on my skin. The difference in the intensity of sensation from before and after the rush was striking.
A&P/2nd jhana -> Dissolution/3rd jhana.
Andy R:
Soon, I started getting some unpleasant tingles and vibrations, almost like very mild, low-frequency electric current. This increased in intensity, until it felt like slightly different frequencies were happening in different parts of my body. I started yawning, and my breathing seemed tighter and a bit constricted. Every once in a while, I’d feel a shift (for lack of a better way to describe them), almost like vertigo in a way, lasting maybe a second or two. I also had anxiety, itches in lots of places, full-body goosebumps, needed to swallow a bunch of times, and had strong urges to move or stop several times.
It was definitely harder to focus on separate sensations, and there were definitely a lot of them happening at the same time -- different tinglings, vibrations, larger longer-duration waves slowly washing over me. It almost felt like I was a cork bobbing in a very busy pool, or I was in the back or a truck driving over a washboard road. At one point, I suddenly felt tightness and fear in my chest and abdomen, and icy coldness flashed through my gut.
3rd vipassana jhana (Dark Night) stuff using the body/emotions as objects of meditation. hard to identify the nyanas, sounds generally like Re-Observation.
Andy R:
Eventually, after quite a while, things settled down, the vibrations and tinglings smoothed out and became much more consonant rather than dissonant, and the roughness faded away. It now felt like I was washed up on shore, and the waves were still hitting me, but at least I had something solid under me. The intensity of this faded as well, and although it still didn’t feel completely pleasant, I felt relief and calmness. I decided to try to see how far I could go with this phase of things, and hung out with the sensations. I tried to note for a while, but kept finding myself losing focus and following the content of thoughts. I’d note again, and then lose focus and eventually realize I was lost in thought. Nothing really changed much after that. I almost felt bored, and was having a hard time finding stuff to examine or note. Eventually I stopped meditating.
4th vipassana jhana/Equanimity, indeed!
Just keep going. Be sure to note everything I bolded. You will keep losing focus & keep coming back, note that, too. Note boredom and sense of pointlessness of meditating. About having a hard time finding stuff to examine or note - note anything subtle that you notice, e.g. awareness, calm, boredom, ease, relief, spaciousness, whatever subtle things you're seeing visually.. there's lots of sensations that make up all of those that you may be taking for granted.
"Eventually I stopped meditating" is the way it tends to end, so set a timer and sit & note until it goes off.
