I think this is about as real as talking in tongues in Pentecostal churches:
How Do I Know if a Deity Is Calling Me?

Question: How Do I Know if a Deity Is Calling Me?
A reader writes in, "There's been some weird stuff going on in my life, and I'm beginning to notice things happening that make me think a god or goddess is trying to contact me. How do I know that this is the case, and that it's not just my brain making things up?"
Answer: Typically, when someone is "tapped" by a god or goddess, there is a series of messages, rather than a single isolated incident. Many of these messages are symbolic in nature, rather than actual "Hey! I'm Athena! Lookit me!" kind of things.
As an example, you might have a dream or vision in which you are approached by a human figure who has something different about them. You'll probably know it's a deity,
