Seeing things when ill?
 

So, I just got over a Stomach Bug (well, hopefully, I think some of the symptoms are returning (and my birthday is tomorrow (and if I get sick again I'm going to miss this concert that happens to be on my birthday)))

Before I saw what looked like an.. Anti-Shadow? (that's all I could think to call it) that seemed to be a figure of a person moving from where my closet is, over to the rest of my room.
When I looked over (I saw it in the corner of my eye) it sort of shimmered before it vanished.

I'm also seeing a lot of random 'movement' out of the corner of my eye (or even just in an area where I'm not looking at anything particularly.

It seemed odd that I would randomly start seeing stuff when I only had something like Gastroenteritis, IDK.

Anyways, Mother said it would be best if I went and got some fresh air to help me feel better.
She's a nurse, and I'm hoping she's 100% right this time.

It's fairly common that when your ill your brain creates things. It's focused on healing you and sometimes cannot make sense of things.

I wouldn't worry too much. I hope you feel better soon.
