That's a very familiar experience. I have been a regular church-goer for 35 years. And for that long, I've heard people regularly talking about feeling a "burning in the bosom", or feeling "promptings" or "impressions" by the Holy Ghost to do something. I don't feel those things and for a long time I thought something was wrong with me because of it.
At the same time, I have had very rare, but very precious, occasions where I felt like the Holy Ghost spoke to me - not in feelings but in direct words, fully-formed, articulate, and concise sentences. Almost always, it has taught me something valuable that I didn't know before. Again, these are sacred experiences to me, but I still wondered why I couldn't feel what everyone else felt.
When I was diagnosed as autistic, I learned that the lines of communication between my conscious mind and my emotions are muted - not as clear as in NDs. And it clicked. Of course God wouldn't speak to me through a medium that He knows I wouldn't hear or wouldn't understand - no more than He would expect me to read the bible in Swahili. For people who are well connected to their emotions, God may speak to them through emotions. When He wants to speak to me, He uses words.
So emotions may be the most common, and the one everyone talks about, but I believe God is capable of speaking to each one of us in a way that we will clearly understand.
