A lot of tropes are shared across cultures. Some of the ideas you have recorded in LSD have certainly been kicking around for millennia.

I hope that you continue to give yourself credit for having written credible characters and scenes - regardless of whether they seem like certain others which came before yours. After all, you did arrive at these things independently.
