Dream is understood as the project, desire or hope with little or no probability of being realized. The levels of dreams can be three: 1- Low (buy a new car). 2- High (buy a house, travel the world). For nationals of many countries these dreams could be very high. 3- Very high (win the lottery, be president of the country). Is it good to have dreams ?
If you didn't have dreams you would die of boredom. They are your connection to the future.(whatever that meansPlease Register or Log in to view the hidden image! ) Mind you ,they do say to "live in the present"
