What does a high transaction fee usually imply? Are we expecting a bull run coming soon, or what? Because the last time I experienced this high transaction fee, the market has been very bullish, so what is it now?

Crazy! I have no other word for it.
I've been wondering for a while what would be next after altcoins, ICOs, Forkcoins, DeFi and NFTs. I guess the next pyramid scheme is making up BS on the Bitcoin blockchain. As usual, a few people will get very rich out of this, and many people will lose money. All I can do is warn against it.
Do people not understand they need some centralized service to "use" their made-up tokens, which goes against everything Bitcoin stands for? So, when they think they have this, in reality they have only Bitcoin dust!
