Water bugs in my dream !!?

I had a dream that included 2 water bugs, and I woke up at 4 AM very freaked out and scared. I went back to sleep and woke up in the morning to find a dying water bug on my bedroom floor. Its the first time I've seen one in my room, and I'm wondering 1- if i subconsciously saw them in my sleep and 2- if it was a sign (lol) but both lead to the question -- where's the other water bug ???? ewww
