Most of the things i feel with my ears and tail have already been said by other people, all i have to add is this: when i'm really happy, hyper, or surprised, i feel like my astral ears (which are kind of on top of my head, not like the physical ones) are trying to pull free, kind of like if someone grabbed your wrist gently and pulled it.
Also, when i'm scared or really sad, the opposite is true; i feel my astral ears go down so much that sometimes it hurts and i have to push them back up.

That's all i have to say for now 3nodding
