Seeing is believing, but sometimes it's deceiving. Do you feel like you've seen this before? A moment of rowing your boat? A second of standing still in the forest? A family gathering of a conversation that's weirdly been discussed before? This and so much more is all tied in to a feeling called deja vu. But, what causes deja vu to begin with? In this episode we'll dig deep and try to answer this question because you were probably too lazy to search for it.
