"Tomorrow, we're all going to die and go to Heaven"

Last night I went in to say goodnight to Trent, this is what he said,"tomorrows the last day, we're all gonna die and go to heaven." He said this very matter-of-factly and with a smile.  I was like, "umm, what?!"  For a second it kind of creeped me out, like does he "know" something?!  My mind raced for a second and I thought, "should we not be driving anywhere tomorrow?"  So after I processed for a minute I went and asked Justin what he told Trent.  Justin had told him, "tomorrow is the last day...of the year."  Apparently in Trent's 5 yr old mind that translated into "we're all dying and going to heaven."  I guess we're going to have to be more specific when we talk to him!!!
