Crazy ass dream I had last night!

So in my dream the entire earth new we were all gonna die, The sun was very unstable for whatever reason and was pulsating and creating massive heat waves that were incinerating things and it was pulsing like a heart beat, was very blinding and hot. Very, very odd dream cause we were all faced with death and no way out. Very real to me I will say that. A movie I would have went to see if it was one wish I could share the visuals and feelings that it produced with everyone.
