It's a common thing....
When your with someone f2f sometimes you imagine of the future events or circumstances which the said someone is present. The imagination can be career, life, misfortune, marriage, murder, delusion, and friendship and uhm similar to what you mentioned.
Hmmm, if we want to have similar gist of what you mentioned.... Is it possible think of marriage with that someone during the marriage? Or, imagining killing someone while you're in the action of killing?
