Can you tell whether Inception is real or not?

First of all, answer the upstairs question about whether Cobb finally came back to reality: First of all, the gyro finally trembled and tottered, and he also saw the child's face. In the past, every time I saw the child in my dream, I couldn't see the face. If you don't think it's reliable enough, I'll teach you a way to tell. Cobb's totem is not a gyro, but a gyro is his wife's totem. Cobb's totem is his left hand's wedding ring. Look carefully, he wears a ring in every dream, but in reality he doesn't! Ha ha! Is it suddenly clear? Ok, to answer the landlord's question, first of all, each layer of dreams can only affect the next layer of dreams, such as the sharp turn of the car, which can only affect the change of gravity environment in the second layer, but not the third layer of snow. In addition, you have to distinguish the concept. It is the fourth dream that they finally return to Cobb's home to save the rich second generation. Cobb's going to Saito alone is lost! ! ! There were two opportunities to KICK back from the hotel (the second floor) to the car (the first floor). The first time, the car hit the railing and they missed it. At that time, there was a scene where the handsome boy on the second floor suddenly flew out in front of the hotel corridor. Do you remember? The second time is the moment when the car falls into the water (note that it is an instant! ! ! ), at this time, the handsome guy on the second floor detonated the bomb in the elevator, and the pretender (Yi Musi) on the third floor detonated the bomb, causing weightlessness at the same time, that is, the synchronous KICK was completed and he returned to the car on the first floor, that is, the water. Because of taking high-intensity sedatives, Saito will not wake up when he dies in a dream. When he dies, he will only fall into chaos (limbo), where there is only an infinite subconscious, where people will forget that they are dreaming, and only when they die in the lost domain will they return to reality. Now do you understand why Saito can't wake up in the hotel? According to the relationship between the dream time of each layer multiplied by 2 times, Saito, who arrived in the lost area in advance, is very old, while Cobb, who went a little late, is very old, but still much younger than Saito. In fact, Cobb forgot his purpose when he went to the lost territory. When Saito took out the gyro that his men had searched out of Cobb, Cobb remembered that he had come to find Saito. Ok, that's it. It's not easy to type on a mobile phone!
