For some definition of real, all these internal experiences are real. Not interpersonal, maybe, but they will have an effect on the person and on how they interact with the environment including other people. Accounts like this also tell you what's possible. It might and probably won't be true for everyone, but nobody is unique enough that it won't be encountered again. So even if it's just one author telling you about his internal world I'd say there is a little more to learn from this.
