If this was a vision... you are precognitive. A fire in a tower building like that is catastrophic for people to see.

Sympathies to London (you've been through sooo much lately!!), and to building's residents.
Not the kind of sight that makes people feel safe.
Make sure that YOUR home is up-to-code, and that you have a Fire Plan in place for yourself, your neighbors. Make sure any family will know how or where to get in touch with you to make sure you're safe.
Tying this with your nightmare dream....
