Besides being with Jesus and my friends and family,.. I picture Heaven to be a place where you can play with kittens and puppies whenever you want to, eat as many sweets as you want without having to vomit, seeing beautiful gardens and waterfalls, and living in beautiful white mansions with either beautiful backyards and beaches by them and always being bathed in sunshine and seeing beautiful rainbow colors. :) While also being able to ride the rainbows and walk the streets of gold.
(Just using my imagination on this one.)
