In chapter 11 of Neil Gaiman's American Gods, Mr. Wednesday gets very upset that Shadow gave away his location to everyone when he's supposed to be hiding in Lakeside.
“What do you think is the fucking point of stashing you in a hiding place like Lakeside, if you're going to raise such a ruckus that not even a dead man could miss it?”
“I dreamed of thunderbirds …” said Shadow. “And a tower. Skulls …” It seemed to him very important to recount his dream.
“I know what you were dreaming. Everybody damn well knows what you were dreaming. Christ almighty. What's the point in hiding you, if you're going to start to fucking advertise?”
This is apparently confirmed in chapter 12.
[…] “Tell me your dream,” said Whiskey Jack.
Shadow said, “I was climbing a tower of skulls. There were huge birds flying around it. They had lightning in their wings. They were attacking me. The tower fell.”
“Everybody dreams,“ said Wednesday. “Can we hit the road?”
“Not everybody dreams of the Wakinyau, the thunderbird,” said Whiskey Jack. “We felt the echoes of it here.”
“I told you,” said Wednesday. “Jesus.”
All this seems strange, because dreams are normally private to the person dreaming it.
Was Mr. Wednesday right, or was he exaggerating? How did everyone suddenly find out about Shadow's dream and his location? What did Shadow do that raised everyone's attention?
