Question: If God or Guru come in a dream, is it real?
It is a good inspiration, but one still needs to practice sadhana and meditation. If such a thing happens, it may be that one has reached a higher state. But ultimately whatever mind's imaginations come, it is an illusion.
God is not sitting somewhere like a person. God is everywhere, all-pervading. All experiences other than this, they are not the Ultimate Truth.
