Ok, this has actually been asked already, but that was 6 years ago, I figure it's time for new opinions.

Let's say (hypothetically, of course) that there was a guy who was so awkward and shy around other humans that he could not get a partner. So, he decides to create a partner in his lucid dreams and be in a relationship with her (it) the same way other people have relationships with other real people. What (if any) psychological consequences would arise from this? Is it possible for him to live his entire life this way and still be happy?

Thanks for reading, I know it's an odd question.
