For which camera? I have a few old C-Mount lenses I used on my GH2 which get similar. Effect will depend a lot on the "life" the specific lens has had. For example on my GH2, the old 16mm lens I have does something similar to this, though it also vignettes so you have to be careful how you light for it. The 75mm I have, however is much clearer looking, but still has a creamyness you don't get on modern glass.
The problem being, when it comes to older lenses on modern cameras you have to test a lot to see what you can get and if you get one lens which has an awesome effect such as that, you may not get any other lenses which get close to that kind of look.
Filters alone won't cut it, but they can get you close. Vantage has a new set of odd filters I just saw, similar to the blu streaks, but now with all kinds of "stuff" mounted in glass which will certainly make some odd flares.
I personally got a "dreamy" like look too with a small piece of acrylic drilled with multiple holes, like a cheese-plate, but of varying sizes which acts like a fog and throw giant out of focus circles all around the image... unless you stop down.
Nets in front of the lens can also cream things up and make them look dreamy, paired with uncoated lenses for the flares you can probably get close as well.
