What does this mean or what do I do i just saw something but my friend that was right next to me couldn't see it but i could still see it even though my friend can't?

This could mean that what you saw was either something outside of your friend's field of vision or perhaps a reflection or illusion that only you could perceive. If it was something unusual or concerning, it might be worth investigating further or discussing with your friend to see if they have any insights. Consider taking a moment to reflect on what you saw and why it stood out to you. If it’s something specific, you might also want to document it for clarity.
