Paranoid.

1.1"Unreasonably or obsessively anxious, suspicious, or mistrustful"

It can be evoke from any things that we are unsure of, such as, future

Tendency to avoid the occurence of the  event, while the fact that the future may be better than those nightmares that often been dreamt of.

Ignore paranoia in self, because future is something beyond our control. Why evoke paranoia in thinking of negativity, while positivity can be generated instead?

Smile and avoid paranoia
