Lightheaded sneezes on my back

Description: I lay on my back and let  some sneezes out! it starts of pretty calm by my the end of it my sneezes get more intense. i sneeze so hard that i start seeing stars. so much snot ends up on my upper lip and i end up feeling even more weak than i did when i started sneezing. i’m glad i have a pillow to lay down on while i sneeze because i’m so lightheaded!
