Dream is from the Old English drēam — joy, music — and later (through Norse influence) the modern meaning of a dream. Dream Renée Kardashian (born November 10, 2016) — daughter of Rob Kardashian and Blac Chyna; named after her father's sister Khloé's nickname for her late mother Kris Jenner's career — "the Dream Team"; her birth was widely covered by E! The Dream Theatre — major Off-Broadway venue. A Midsummer Night's Dream — Shakespeare's comedy (c. 1595). "I Have a Dream" (1963) — Dr. Diana Ross's "My House" — Dream-themed song.
Dream does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Dream reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
