What does my dream mean? Islamic reasons? please help!?

so, i had a dream last night.. me, my sister, my uncle, my cousin, & my grandfather (late) were in my old house.. we moved about 5 years ago. we were taking stuff out of my room & there was an elevator right outside my room, we decided to take that downstairs.. we had to put in a code for where you wanted to go. we put in the code for downstairs & the elevator kept going & we saw a map in front of us that landed in 7 different locations.. we had no clue where we were. we were all very worried because we couldn't find out a way to go back.. my uncle and i left the elevator to find out a way to go back and when we stepped out, we were in an abandoned children hospital & my grandfather, my sister, and my cousin were talking in the elevator & then all of a sudden we were in my basement of the house we live in now.. our carpet was very wet & someone jumped and our carpet was laid across really black water & there was a bunch of skinny, green, long snakes.. we were confused but i was the only one that was VERY scared & someone came in and said we have to eat them but i didn't have to.. a few people started grabbing a hand full of them & one snake kept hissing at me & tried to bite me but didn't.. i didn't even try moving away but i was really scared. and the girl sitting next to me ate the head off and ate the rest of the snake.. after that there was no snakes left & our basement was back to the way is was but we had a few puddles of water left.. what does all this mean? i really want to know!
