Unclear dreams

Really frightening… But, you know, in dreams, timing is extremely different from the one IRL. That’s why, I’m asking you: Can it happen to someone to have thousands of these FA’s and kinda “get stuck” in his/her dream ? It could be that a year in a dream is just an hour IRL. So, can someone have thse FA’s which are soo very real for a whole dreamyear ? That would be the most frightening nightmare ever…
