He's referring to nightmares in my opinion.

Ever heard of the expression, 'wolves at your door'? Well, it's kinda like saying something's brewing, or in the works of going wrong. In this case, something to bring up nightmares.

Well, in this song, now they're 'in the house'.

Mama is also something he's using in a child-like perspective. Cause when you're a child and you wake up from a bad dream, you call to your mom. :)

'mama they won't let me out mama they're mating at night mama they wont make nice'

Obviously, he can't escape them. By 'mating' he simply means that they're growing either more 'vividly' or even in numbers. And they won't make nice, as in he just can't figure out how to get rid of his nightmares.

He also describes them as tearing up the house and running around.

Perhaps he means that these problems, these nightmares, are just destroying everything, changing his perspective and eating away at his mind. He just can't relax with them around anymore.

And again, he refers to his 'mama'.

'mama there's wolves in the house mama i tried to put them out and mama i know you're too wise to wait till those wolves make nice'

He's looking at his mother in a child perspective again, where he thinks her too wise, and strong to be buffeted by these horrible nightmares, that she won't try to make amends with these nightmares or stand for it at all.
