Sensations are just that - sensations. There is no right or wrong.
It's like telling someone they aren't sad enough. HUH? This guy's mom just died, and you're saying he's not sad enough? Maybe because of age, maturity, etc., his depth of feeling isn't the same as yours, but how do you justify telling someone how they're supposed to feel?
Definitely, a MAJORITY of people have similar sensations when singing. Since these are experiential, we can't always rely on them to sing.
When I found nasopharyngeal, forward, bright, etc. resonance, it was right in my face. My nose felt like it was vibrating. Instead of finding the sound that accompanied the feeling, I just chased the feeling. I was SO NASAL my next lesson! My teacher laughed and explained how to find it on my own.
"Right after our lesson, go find it. An hour later, go find it again. Keep doing this until I see you next time. There's a chance you won't find it again until next week. If this happens, don't worry about it. I can tell if a student practices even if they weren't able to get the sound from last week. I won't kick you out of your lesson just because you weren't able to find a new sound."
The WORST part of this is that sometimes you do need to chase a sensation like breath support! Are you engaging the correct muscles? Some people are also strong enough to not feel the muscles engage!
There always is and isn't an answer, and that's what makes singing/teaching so fun for me!
Know yourself! Grow yourself! :D
