It may be something that will happen to the person who is having the feeling but it may also be to several persons, as might occur with a highly destructive earthquake, for instance. 

The word or phrase would be used in the following sentence: “I’m no spiritualist but I have a feeling ---------------.  I hope it’s just a feeling."

EDIT - The phrase I'm looking for conveys a much stronger feeling than "I have a bad hunch". It is about something **catastrophic** which the person feels is "going to happen **in a few minutes**".
