What is the omen that a white butterfly flies into the office and lands on my bed for a long time around seven o'clock in the evening?

At about seven o'clock in the evening, a white butterfly flew into the office and landed on my bed for a long time without warning. It was normal. Butterflies have phototaxis at night and will fly to places with light. Butterflies will find a relatively dark place to rest in the room. Dark places will make resting butterflies feel safe. Their fur is black. When a butterfly thinks it is a dark place, it will rest on its head, which is its own instinctive reaction. Butterflies are most active when the temperature is high in summer. Butterflies like warm environment.
