If you wanna read about what some other people can meditate into I'd suggest: Siddha Yoga's Swami Muktananda's Play of Consciousness, Swami Sivananda has a Spiritual Experiences book, anything by Ken Wilber [Spectrum of Consciousness, A brief History of Everything, or ESPECIALLY One Taste: the Journals of Ken Wilber], and some other stuff I might think of later.
Personally, I've meditated for like maybe 10 years now??? Back in the day I was much better and would go into samadhi [meditative absorption] 29 times out of 30. I'd describe some of those experiences as "decontractions or ungrippings" in consciousness followed by resting in whatever particular field of consciousness.
Now its like my mental wanderings go down dramatically and I can focus on one thing and when I do things go into "flow states" but its not focused enough or relaxed enough to lead to samadhi. I can regularly: feel big, feel small, vibrate, feel like "my soul wants to leave my body", see colors, see images, feel visited, have moments of "clarity", but for the most part its a way of relaxing or slowing down the stream of thoughts. I consider myself an intermediate practitioner of taoism, buddhism, and hinduism/yoga with occasional forays into advanced states/practice. That's my short answer.
addition: I didn't thinkof it under meditation since I can do it more or less anytime, but since it ties in I wish to point out that I can sense and "use" numerous of my chakras, as well as sense and "use" several of my subtle bodies. But those do have more going on while I meditate, and in particular its like they energize, unify, and go into "harmonic convergence" if you will.
