I was one of those kids who was always told I was daydreaming too much and I should “stop daydreaming”. I still do it. And I still think it’s a positive thing. (Maybe not when you should be paying attention to something else, like how to work out a square root of blah, but in appropriate moments.)
It’s just one step away from visualising, and visualising leads to manifestation.
If you’re a daydreamer like me, remember to also take steps to making those lovely little dreams come true. As a starting point, you could do a vision board. Give it some love and energy and then stick it up somewhere or put it away (it doesn’t really matter, because the doing was the manifestation energy at work).
There’s nothing wrong with daydreaming, but if you’re going to dream about winning the lotto, make sure you’ve bought a ticket. ;-)
