Strange dreams, zombies and mosquitoes hold the key

Recently had a couple strange dreams:

1. Apocalyptic, zombies have taken over the world...

2. Kate and I were searching for Griffon in a house. We suspected the owner had taken him, but he continuously denied it. Kate had the idea of capturing mosquitoes, and examining the blood they sucked for traces of Griffon's DNA.

Thought a very creative suggestion, and have no idea what it means.
