Like a bubble of dreams,
Like dew and electricity,
We should look at it this way.
This dream is an illusion, which is simply a delusion. According to Buddhist theory, what all beings see from the outside is illusory. "Dreaming of being friends with tigers" means dreaming of "false self" in your heart. These phenomena are called "self-illusion". As long as you don't cling to fantasy, your "true self" will emerge, which is what Zen calls "seeing nature from the heart" Think of everything, think of everything! Only by eliminating delusions can wisdom appear and troubles be removed!
According to Taoist theory, this is your deputy god, representing inner fears and struggles, which may be related to the recent stress and frequent troubles in life. As long as you learn to let go of persistence, calm down and purify your mind, look at things like a mirror, and get rid of everything is great wisdom!
