Depending upon when you registered the domain, and set the nameservers to point to Dreamhost, you are probably in the period of time it takes DNS to be updated across the internet. This can take from a few hours to several days, so you just need to be patient.
If you want to view your site before DNS has updated, check out the Dreamhost Wiki article on Viewing you site before DNS changes.
Did you buy a hosting plan with Dreamhost, or just register a domain? It’s not going to work without hosting.
If you have a hosting account somewhere else, you can still register the domain here, but you’ll need to change your nameservers to whatever your host specifies.

Thank you for the support! I’ll be more patient and wait.
