I think you might have to rephrase your question as well, perhaps by making it a little less vague.

Are you talking about feelings generating by the dream, or feelings you felt upon waking? Are those feelings physical, emotional, intuitive, or all of the above? I think if you just ask how someone felt, then, with the exception of nightmares, the answer will likely be "I'm not sure," so people won't bother responding. ... By extension, I think that a lot of dream researchers seem to think that the mood of most dreams are negative, because those are the only ones they hear about.

For what its worth, my feelings in my last dream included happiness, satisfaction, concern, curiosity, and a few other emotional, tactile, and possibly physically-influenced feelings. Just like life, dreams can be very complex things, and to ask people to encase their entire experience in one feeling might be confusing.

I hope that made sense; good luck!
