Living is easy with eyes closed, misunderstanding everything you see.

Can someone please help me figure this out? Earlier today while I was trying to relax I closed my eyes and saw a Black Widow clear as day shortly after that I saw the black widow bite someone on the hand and then it ran across a city roof top jump off and begin to swing to another building then it ended as quickly as it began. I neet to know what if anything it ment if anyone can help pleas do.
