Is there a certain religion that believes in dimensions? do you believe in dimensions?

i personally think that when we die we will enter another dimension of reality, and these dimensions are unlimited, kind of like you are in a sleeping state in a dream. Think about it your consciouness exceeds on a whole other level, and i dont believe that when we die our consciouness will die with us, i cant envision myself dying and being non-existant, i would prefer people of non-christians to answer this for me please i dont mean no offense to christians i just dont want to hear that God is the only answer to everything. Well what im trying to ask is what do you think about this and if there are any other people out there that believes in the same.
