Yes, very much so, but it doesn’t mean it’s true. I had a feeling that I was near my death, many times, but it wasn’t death that was coming but something else. You can’t know when you are really dying - once you’re dead there’s no one to know you’re dead. What you’re experiencing is fear, and your mind is making a story about death to rationalize your fear. To the extent possible, don’t be afraid of your fear, allow yourself to experience it, but don’t buy into anything your mind tells you. If you get lost in your mind, just do a quick reality check - look at your body, feel your hand, see that your body is just fine. It’s just your mind playing tricks on you, it can feel as real as anything you have ever experienced before, but if you don’t do anything stupid to your body, it will take care of itself and you’ll be fine.
