I felt the same problem with the Dreamwear mask. When laying on my side, it felt as if the air flow was blocked on one side, even though they try to tell you that it will deliver all the air flow to the other side, but I couldn't tell. Also, the nasal mask had to be adjusted several times during the night to stop leaks. This defeats the purpose of getting a good nights sleep. I'll stick with the P10.
My experience with the DreamWear is similar to yours. After nine days, Leaks were higher than with my main mask, a P10. Minor changes in sleeping positions would cause the nasal interface to be dislodged. Experimented with strap tension (where less is usually better), but no help.
Other data such as AHI and snores were no different between the masks.
I've gone back to my AifFit P10, with the Swift FX Pillows mask as secondary.
Here is my post yesterday on the product review forum:
I too gave the dreamwear mask a trial run. I'm not a fan of it at least as compares to the P10s. I found the noise and air volume coming out of the small rectangular nasal vent hole in the front of the cushion too loud and too much. It wakes me up a few times a night disrupting sleep. Although I had one 0.0 ahi night I didn't feel as rested as a solid night with the p10s. I'm going to keep it as an emergency backup though. The p10s are amazingly quiet and the results in terms of how I feel in the AM (the ultimate test) are unsurpassed.
I don't have any vent noise from my DreamWear mask unless I get a sheet or hand too close to it. On my Wisp I would get air in my eyes and was constantly getting tangled in the hose--and it hurt my nose. I get leaks with the DreamWear but not enough to trigger a large leak--a few nights SH has warned me of a major leak. This usually occurs if I pull the cushion up off my face to re-position it. I also don't have the problem of cutting off the air--or at least not getting enough--so this must be a positional thing. I've loosed the mask--you have to have it loose enough so it doesn't push up on your nose--and this seems to work pretty well.
I have a couple of issues with Dreamwear after two weeks of usage:
1) I have developed an open sore at the base of the septum on my face. Based on what I have read in other threads, I need to try some HPA Lanolin cream.
2) The mask is a little noisy but I have gotten use to that.
3) I am very sensitive to air being reflected by my bedding back into my face from the hole in the front of the mask. Since I normally sleep in a room that normally is about 50F degrees, that reflected air is very cold! The room is not going to get any warmer this time year as I am in a log cabin and all the heat is provided by a wood stove in the main room.
4) At times when I roll over, it seems like the mask is leaking. However the PRS1 that I am using does not record a leak. BY shifting my head a little bit, it seems to go away. I tried feeling for a leak but couldn't find any. It may be just a change in position of the hole across my nose giving me the noise and feeling.
All of that said, if I can get the nose irritation under control, I am not giving this mask up: its benefits outweigh the problems. I specifically like the hose at the top of the head, the comfort of your he mask during use and the ability to sleep on either side and change to the other without problems.

If you folks like the lack of stuff stuck up your nose, try the Nuance. It's a good mask with a good seal and has real headgear that adjusts.
