The College of Glamour bard's Mantle of Inspiration feature reads as follows (XGtE, p. 14; emphasis mine):
As a bonus action, you can expend one use of your Bardic Inspiration to grant yourself a wondrous appearance. When you do so, choose a number of creatures you can see and that can see you within 60 feet of you, up to a number equal to your Charisma modifier (minimum of one). Each of them gains 5 temporary hit points. When a creature gains these temporary hit points, it can immediately use its reaction to move up to its speed, without provoking opportunity attacks.
Since technically you can see yourself, you can see your target and your target can see you. As such, when using this ability, can you target yourself with it?
