Bad Guy Bleeds Black Blood, Walks Down Invisible Steps

What's the name of the 90's movie that has a baby who can crawl as soon as it's delivered and it chases it's mother into the bathroom?

In another scene, the bad guy walks down a pair of steps that are invisible.

In another scene, a guy at the gas station said 'you're bleeding black blood' and the bad guy said 'then give me some of yours' and kills him.

Any ideas?
