Is it possible for someone to genuinely lose track of reality because of LD? Could i really LD about some sort of sedative so that I was dreaming in a dream to spend weeks, months, years (subconsciously)? And if it were possible, could i sort of do what Cobb did in Inception and spend my entire life with someone, even if it weren’t real? Just wondering… I’m really working on LD, ive started reading and studying, and learning about it. I’m consumed by the idea and i Have been working for a short amount of time on LD. Planning on working at it till i can LD at will.
Well, there is people who can spend months in a LD, and there is people who live a completely alternative life to reality, in dreams. So I’d say it’s completely possible ^^ and it is also completely safe, after all everyone wakes up at some point in the morning 
Good luck on your Quest! 
I don’t know. You tell us.
How do you know you won’t wake up at the end of this?
Ok. Whether or not I will actually wake up from this subjective thing called reality I have another question. How would I go about Spending years months whatever in A LD? And people really do choose to live there lives in a dream wpd? This idea this concept consumes me its all I can think about I want to start LD adap. What techniques can I practice to try to LD in the afternoon n evening? What technique is best when I go to bed at night?
As for learning how to prolong a dream, you can learn from the best
As for living an alternative life, that is both a conscious choice, and a matter of practice. It needs some motivation, and also willingness to remember the details of such a life, after that, you may want to learn how to incubate a dream you can look it up on Google, I guess.
EDIT: dangabbit, I forgot the Writerscube link.
People all over have extended dream length, just search around the forum topics. As for the alternate reality thing, its really up to you. In a dream, your imagination is the limit, so you could create your own people, places, things, rules, ect. and make your own little world. If you couldn’t extend dream length, get better dream recall, and remember where you left off in your dream.
