Why do you have three or four different dreams in one night, remember them all after waking up, and try to interpret them?

People have many dreams every night, but they don't necessarily remember when they wake up. However, if you happen to wake up during REM, that is, if you wake up in a dream, then you will usually remember your dream. You said you had a lot of dreams, and it felt like a long time, but in fact it probably happened from your last REM stage, because the sense of time in dreams is different from reality. As for your dream, there seems to be a feeling of anxiety and confusion, which includes escape, exploration, discovery and specious truth. I don't know if there are any related events in your life, but your dreams may remind you of these problems.
