I have pondered that myself.

Yes.. I had a dream earlier than wherein I had deja vu approximately the equal dream. In the dream I all of a sudden felt like I had dreamed it earlier than after which I grew to be conscious I used to be dreaming which used to be much more insane! I nonetheless went via the dream however I knew the whole thing that used to be going to occur earlier than it did on account that I might recollect dreaming it earlier than.. then I proposal I aroused from sleep however I wasn't wakeful relatively I used to be nonetheless napping, I simply stopped being conscious.. and I dreamed that I used to be considering my dream deja vu, and goals inside goals and what I could do whilst I aroused from sleep.. then I relatively aroused from sleep and I used to be stressed... lol

Dreams ( not all ) do have relevance. They kind of sort out and work through your past or present life and it is always related to real life. We have them be cause they rearrange what you have experienced during the day. They kind of make some order in the chaos. Without them we would probably go crazy.

thats an interesting question....I don't know why people have dreams, but I think it's just your brain working while your body rests. almost like it's keeping itself busy. I know that isn't an intelligent answer, but it's the best I can come up with :p

We dream to keep the mind active is one theory. To keep it working and make more connections. and then you have Freud with his unconscious desires. The correct answer is that we don't know for sure.

We dreams to protect our sanity It had been proven medicaly

nobody knows for sure. Some say it's an out of body experience, some say that it is what we most desire, could be hidden messages, could be nonsense.

Because peoples mind are constantly active.
