Unironically, I have a very early memory of seeing Luke floating in the bacta tank wearing what to my young eyes looked like a diaper, and I remember feeling such an intense jealousy and longing
I just think it must feel good to be suspended in the tank. Warm, safe. A thick layer of reinforced glass separating you and the real world. Weightless, no pressure on aching joints or weary bones. Free to curl up in the fetal position or hang free. They can't get you here.
