Overheating: Achievement STEAM of Assassin's Creed Origins

Run around the desert at midday to trigger hallucinations. For example, in the territory called 'Great Sand Sea'. After running around for a while you get RANDOM hallucinations. One possible hallucination is the raining bugs (it's a rare one). Just keep walking in the desert until you trigger it. You can't trigger hallucinations in the morning or evening. It works from midday to afternoon.
