Standstill?

A while ago I posted my story about how I sometimes hear voices when I'm about to fall asleep and how I sometimes see images (visions?) flash across my mind. I started researching psychic and spiritual abilities and I learned a lot of new things. I also started meditating, which helped me a lot. I realized that, as my knowledge of the spiritual and psychic world grew, I started experiencing more things. For example, I saw an image of a noose and, a few seconds later, I felt as if something was pulling me up, around my neck. I felt as if my neck was in that noose. Soon after, the sensation stopped. Then, another time, I felt a hand grab my arm tightly. I heard friendly voices talk to me. I even had a very small conversation with one of them. It was nice because it was the only conversation I ever had with an entity (or what I'm assuming was an entity).

Experiencing all of these things was really nice and it opened a new world for me. Unfortunately, I don't experience that many things anymore and it really bothers me. There was a time where I would hear voices and see things constantly. Now I'm lucky if I hear anything at all.

Does anyone have any idea what could have happened to cause this? I was trying to develop the abilities I had and, in the beginning, it was working. But it seems like I've reached a standstill. Or like I seem to be going backwards. Does anyone have any advice for me? I've heard that a person's abilities never go away but they may stay dormant for some time. Is that's what's happening to me?

Any advice would be greatly appreciated. Thank you!
