Dear Lauri,

I dreamed I finally got my hair cut with a new stylist and even bought a new brush from her but realized afterward that I'd forgotten to tip her. – Jill, Syracuse, NY

Lauri: Hair in dreams is all about your thoughts, ideas or plans in waking life because – like hair – our thoughts, ideas and plans sprout from the head. Have you changed your mind about anything recently or had a change of plans? Have you been working on changing your mindset? The brush suggests you have sorted out some tangled or confused thoughts. Let’s also see if we can figure out the tip in your dream. Did you get a tip in the form of advice recently, perhaps a nugget of advice you had forgotten about but realized it was "worth" it?

Jill replies: Yes! I was trying to buy a house but am realizing it may be better to rent a little while longer. And as far as the tip goes, my current partner reminded me how difficult it may be to sell a tiny/cheap house. Why buy now just for the sake of buying instead of just renting for another year? Makes sense. Thanks so much!

Fascinating Sleep Fact: In 1965, a San Diego high school student named Randy Gardner stayed awake continuously for 264 hours, an eleven-day feat documented by a team of researchers from Stanford University. He soon lost the ability to add simple numbers in his head and became increasingly paranoid, asking those who had promised to help him stay up why they were treating him so badly. When he finally went to bed, he slept for nearly 15 hours straight.
