As I've mentioned before, she's very smart and loves secret messages and posts them often. People who don't understand this are making a big deal out of it by assuming that she is crazy because they feel insecure about it. That is really missing the point and disrespectful.
To begin with, she writes in a cryptic way because she is not obligated to post in a way that everyone in the world can understand. So it's rather natural that people can't understand the meaning of her posts. She writes in a way that certain people will understand.
All I can say now is that her puzzle-like posts have meaning, and she's sooo smart and poetic and an artist. That I'm even in awe of her.
Apart from that, she has explained many times why she makes posts like this one. Have you forgotten that?
She once wrote that she was sick of her father and Robin coming to her dressing room to monitor her every time she got ready, which took hours every time during the conservatorship, and that's why she likes to post on Instagram, where she can do everything by herself, and she also wrote in her book to regain her artistry that was taken away from her.
