Keep watching your dreams. When you were a child, you liked to play at grandpa's house. It is your wish to stay at grandpa's house for a while. Your dream fulfilled your childhood wish in the form of flood. You said, "Grandpa, please use my pen." This sentence should be what you said before. Anyway, it is not necessarily the memory of what Grandpa said. It's just that you think Grandpa is angry with you (superstitious thinking) so Grandpa won't let you touch it. "I'd better use this pen." You said that. Don't you draw? The pen that appears next to you is to cover up your greed. There was no pen before, that is to say, you only wanted that pen because it was new. You didn't want grandpa to use it, but wanted to have it yourself! This is what you did when you were a child. Developing photos is just a prelude. The reason why you have been uneasy for so long stems from a mistake you made when you were a child. If you can remember this and forgive you at that time, you won't be bothered by grandpa's dream. You can freely associate memories through new scrawled brushes and things like that, and you will definitely remember them.
