Being able to go back in time =D

I've always wanted to feel what it would be like to be in World War II, so since i had a lucid dream last night, i focused alot on War and fighting then when i opened my eyes i was in a bunker with a rifle, fully kitted out as an American soldier! It wasn't really realistic (kinda blurry and sometimes slow) but i was running through fields, bombs going off and distant voices yelling and all kinds of things. It was really cool.
