What Causes Sudden Altered Sense Of Consciousness And Inability To Recollect Events?

Please forgive the story. It is the issue. My husband said our oldest forgot to grab a container and he would go get it. So he went outside and retrieved this container, comes back in, and goes to hand it to me. I grabbed the other end. He wouldn t let go and is steady staring at me. I thought he was playing, so I told him to knock it off. He didn t answer and still wouldn t let go...while still staring at me hard. So I put the sponge I had down and went to grab it again. He dropped this container before I got to it, steps to the side, kind of shakes his head, and asks me what Im looking at. ... ... I asked him what he had just done. He couldn t answer me. I told him to stop messing with me. He still acted the same, so I repeated what he had done. He told me our daughter got the tupperware and he had never gone back outside. When I tried to argue he told me to stop lying. If our oldest hadn t seen the whole thing from his back... I would swear I was crazy. Is this maybe just stress? I don t think I can get him to go to the doctor. He doesn t believe me, but I am freaking out.
