Where can I find this Discipline that allows a Vampire to disbelieve in sunlight, stakes, etc. so strongly that it can ignore them?

I had a character around 2001 that I was working on for a game that fell apart, and while reading through some book I came upon a very high-power ability that allowed a Vampire to disbelieve in something so strongly that it didn’t exist for it any more. This could be anything, including doors, which would allow for entry into any room, or blood, which would be less than bright.

I have not been able to find this particular Discipline since, and I would love it if someone can tell me what it is and which sourcebook it’s in.
