Hi, I am a young adult with general anxiety. I've had "typical" panic attacks only a few times in my life. By that I mean having the physical symptoms like shortness of breath, elevated heartrate, etc. 

Anyways, sometimes I have these strange mental episodes in bed. I had one just now so I want to get y'alls insight. This is the only way I can describe it, but if you've experienced it, you will get it lol. It's like my mind itself is jiggling and zooming fast while feeling incredible dread and inability to form coherent thought. Feeling relatively calm at the same time. The physical symptoms don't accompany these for me. As an adult, these episodes will pass within a minute or two. Although, during my childhood, these would happen often and sometimes very intensely. To the point of being very traumatizing to little me.

It definitely sounds like a panic attack after writing this its just not what I've always associated with them. Curious if anybody has similar experiences or insight.
