Yeah that was the whole point of Cap's dream/vision. Everyone else on the team who gets mind fucked by the Scarlet Witch has these horrible terrifying dreams (Stark sees himself failing to save everyone else, Black Widow sees her training as a ruthless assassin again, despite now having an almost normal life with friends, Banner probably sees things that make him rage and go full-on Hulk mode which is why he wipes the floor with Wakanda, Thor has visions of Ragnarok...) but Cap is kind of immune to that terrifying dream, as he should be (in the comics his willpower is so strong he can resist mind control). He simply wraps up a loose end (his dance with Peggy Carter that he always regretted missing) and yes he also experiences some bad feelings (as was said above he realizes he has no place left in the world.. no appartment he wants to buy, none of the old friends anymore, no purpose for his personnal gain) so he just settles to become a full-time leader.
