The entrance seemed to vibrate, that whole cacophony surrounding it getting louder and louder - like it was taunting them, beckoning. Well, if it wanted a battle then Dan would give it one - a battle of wills, perhaps, since simply blowing up the doorway and shattering the clown's mouth by stuffing a stick of dynamite in there wouldn't actually happen.
It kills monsters, if you believe it does, he echoed, stepping forward. The feel of it was sinister, chills and a temperature drop and the scent of smoke and bitterness suspended in the air. Something you didn't forget. I'll open the door and whatever comes out, we're just going to push back as hard as we can - picture yourself ripping it apart so it's not whole anymore. Cast it out of your head.
Then he went for the door, which was sealed shut - Dan dragged his hand over it, looking for an opening or a weak spot. And telekinetically grabbed one edge of the door and pulled, wrenching it apart.
