I really love some of my dreams, and I have them very frequently(sometimes multiple long ones per night that I can remember) so I guess in this I'm very lucky. In dreams you can be anything, anyone, and do anything, though for me I'm never really in control of the dream, just along for the ride. Sometimes they're grand adventures of heroism and danger, sometimes thrilling tales or mystery and suspense, rarely of a simpler, more 'naughty' theme. Very occasionally it'll be a "nightmare" but those I've found end quickly, and even then can appreciate them.

Thank you dreams for letting us experience life greater then what we are able to experience in the waking world.
