You mean dream as in
-- most likely attainable,
-- maybe if I'm lucky attainable
-- most likely attainable only in my dreams
answers will probably vary as people interpret it in their own way.
For me, I hope to have a nice home gym in a few years. I don't have a house yet, but am thinking of either getting one with a large basement so I can set up a gym in it, or getting a place with a big backyard so I can have a separate gym built in the backyard. I imagine nice hardwood floors with a high ceiling and good ventillation, with a large screen tv, sauna, washroom, small kitchen, etc...and of course lots of great exercise equipment. Then after I wake up I could just go to my personal gym, do some cardio on gym quality machines, and then some strength training...not to get big or anything, just so I can keep from getting too feeble as I get older...or later in the day if I feel a bit lethargic I could do a bit of cardio or a few reps of whatever. Or I could watch a show on the big screen tv and after an hour or so push the pause button, do a few exercises, then get back to the popcorn and movie. I could be a relatively fit couch potato.
I already have some pretty good stuff but ran out of room so can't buy any more. One of the coolest things I got so far is this.

Not a huge dream but pretty sure it will be attainable in a few years. I know you don't need lots of equipment or even any equipment to get fit, I just think it would be cool to have, and I enjoy working out on solid gym quality stuff...considering I was broke about 5 years ago, even selling my old used car to help me buy domains, this is a dream I'd feel pretty good about attaining.
