Putting subdomain

I recently registered a domain with dreamhost. However, I want to transfer that domain to another host. When the domain gets transferred, what will happen to my dreamhost account? Is it possible to get a subdomain.dreamhost.com for my account?

In the Panel’s domain tab
you can create new domains and subdomains. Just write “yoursubdomainhere.dreamhosters.com” or “yoursubdomainhere.yourdomain.com” in the box!
