You have several vivid visions. In the visions a person/entity tells you that s/he is God. When this happens you are awake and you have not deliberately ingested any drugs. During these visions you feel clear headed and peaceful. This person/entity is not frightening.
1. Do you accept this vision as from God? If so, why?
2. Do you think you are having cerebral or chemical or emotional issues? If so, why?
Regardless of your answer.. could you be sure either way? Would you seek pyschological counseling just to make sure it's not a mental breakdown? Or seek spiritual counseling for help if it IS God?
