Even if you believe in Buddhism, it is meaningless to dream about the image of Buddha, which is not necessarily the so-called auspicious. Because it is clearly stated in the Diamond Sutra, "Everything has its own way, like a dream, like a bubble, like dew, like electricity, and it should be treated like this."
Dreaming of the image of the Buddha without believing it is not necessarily "predestined relationship with the Buddha", so there is no need to constantly hint at yourself and force yourself to have religious beliefs.
But it's good to take this opportunity to learn more about Buddhist thought.
