is dreaming during sleep an indication of good, undisturbed sleep or bad, disturbed sleep?

I have heard both explanation, and would just like to know which one is actually true.

thanks a lot in advance

dreaming mainly occurs during the REM(rapid eye movement), every human being have a certain amount of REM sleep. Dreaming is either good or bad, it is just a way for your brain th shuffle information, unless you are having problems such as nightmares, there isn't much to worry about.

I don't dream anymore, like when i sleep its just blank. I use to always have different adventures in my sleep when i was younger but now i get nothing.

During my school year, i dont think i dreamt much, but since summer started ive been dreaming since day 1, i heard that when you dream a lot that means your getting a rapid growth spurt soon.. i think i read it somewhere and my friend who is 6'6 told me that when he got his growth spurt in gr 8 or 9 he dreamt a lot during the summer and stuff.

please tell me thats true plus everyone dreams between 10-20 times a night but just doesnt remember all of them its on a website

o m f g!!!!!!!!!! its summer now and since yesterday ive been drinking 1.8l - 2l of milk because this basketballer drunk 1.8l of milk during high school and he got a mega growth spurt of about 8 inches. and im 12 and was 4'9.5 since a week ago or maybe more but 2 days ago i noticed my phumb has got biger which is amazing and i think im now 4'10 or 4'10.5 at night and i havent grown for ages and have never had a growth spurt and i think if i carry on bike riding intensely and have lots of protein and dairy products p.s ive enough protein with dairy products alone i need to squeeze in fruit and veg and meat and fish and drink 1.8l - 2l of milk every day wich i already doi hope to get a masive 8 inch growth spurt. plus for the last few days ive been gaining weight coz ive been eating alot and hopefully getting taller and plus the freaky-ish thing is the last few days ive been dreaming a lot do you reckon these are the signs im gonna have a massive growth spurt because its about time i started to grow and i think im gonna sprout coz of all the growth i could of had maybe to grow a lot right now wish me luck im also gonna start swimming soon when i learn to do swimming and breaststroke. thank you wish me luck
