I have had this reoccurring dream as as far as i can remember

im 17 now but i keep getting a really wired dream that i dont even understand whats happening.but here goes

i have this dream where i walk into my nana and grandads attic/loft and it looks like it does in real life but there's a piece of Lego on the floor and i decide to start chewing it. It then turns into a lego rubber wheel which while chewing gets bigger and bigger and the rooms starts growing

its sounds really wired i know but its really quite a traumatic dream for me and i dont know why....

Any ideas whats so ever would be greatly appreciated!
