Pay attention to the tingling and wait to see what happens

The tingling turns out to be Hermes, the messenger of the Gods trying to talk to you. 

He says "Odysseus this is Circe. She is a sourcerer. You will need protection"

He tells you to eat a plant called Moly to protect you from her magic.

Hermes is a messenger of the Gods but he is also the God of Trickery.
You think he could be trying to trick you.

What do you do next?
