<p>How the guy making the linked videos might have achieved those effects of creatures appearing behind him?</p>

<p>Here are the two videos I am refering to: <a href="https://www.youtube.com/watch?v=4qT2nHZ5mwc#t=1m0s" rel="nofollow noreferrer">see this</a>, or <a href="https://www.youtube.com/watch?v=e_k-yLShHC8#t=0m50s" rel="nofollow noreferrer">this</a>.</p>
