what will happen to all your possessions after you pass on

does anyone ever think about this or worry about it? what should i do?

i live in a little flat but i have a lot of 'stuff'....a lot of posessions...books, clothes, my computer, dvds, blu-rays, my iphone, hard drives, doesn't sound like too much compared to others but its a lot for a small one bedroom flat and the posessions mean a lot to me.

so eventually when i pass on, what will happen to all my gear/stuff? is there anything i can do to make sure it all goes where i want it to go?

can i be buried with all my posessions?
