Well, generally speaking, according to your situation, I have to say that you may get Blepharitis. And there is nothing to do with night or day, blepharitis can occur, so you need to pay more attention to it. First, you should know that It is a common eye condition, causing the eyelids to be swollen and scaly-appearing at the base of the eyelashes. And when scales become coarser, the surface of the eye becomes irritated and forms crusts. And if this crust falls into your eye, you may feel like you have "something in your eye" and feel discomfort in your eyes. Also, you feel crusty in your eyes, just like what you said. And that can be caused by many factors, such as eye infection. For your situation, you should take some cold compresses at first, and then go and see the eye doctor as soon as possible.
