Inception

What did the totem moving at the end mean? This was my first time watching it, so I might need to watch it a couple more times to understand it. From what I know, the totem continuing to spin would mean that they are in a dream, but the totem falling would mean that they were in reality. It cut off so we never really get to know truly what was happening. I’ll watch the prequel soon!! LOVE PSYCHOLOGICAL THRILLERS
