I have actually thought about this at length before. I feel like a lot of people would say yes to this but I feel like, they haven't actually thought it all the way through, I mean it is only hypothetical. For me, I ended up deciding that, I would do it. I thought about it two ways, and this way is actually more beneficial, that it happens in a single night's sleep. This way in waking life, I wouldn't be missed, so I wouldn't feel any guilt for that. Although, I did end up after a long period of thought deciding that I would also do it, even if it meant a coma and that I would be missed. But, really I was able to rationalize it like this: Everyone spends their life doing whatever they do, to what? I feel that mostly it is, to achieve happiness. And, anytime I've ever been in a lucid dream that's all I've ever felt, is happiness, and a sense of being care-free. Now this isn't to say that I wouldn't miss waking life, I very well might. But, I feel like if I was in a lucid dream for eternity, that I would be able to come to a state of eternal happiness, and what more could you ask for in life?
