Bhagavad Gita, Chapter 11, Verse 45

Overjoyed am I to have seen what I saw never before; yet my mind is distracted with terror. Show me, O Deva, only that Form of Yours. Have mercy, O Lord of Devas, O Abode of the universe.

Two real, opposite feelings are named here together, genuine joy sitting right alongside genuine fear.

Arjun doesn't pretend the vision was only wonderful or only terrifying, he holds both as true at once. What he asks for next, the gentler form back, comes from that same honest mix.
