Does anyone else get overwhelming panic attacks?

I have been following this for quite some time. Have had interest in the topic since I was a child. But as of recent, the past few years or so, I get random occurring panic attacks directly related to NHI.

I know nothing about them, and have never had an encounter. I had one of these panic attacks this morning when I was walking to my car to leave for work. It just feels like an over whelming feeling that I’m being watched, like something is there present with me.

The presence feels very unfriendly and I do not welcome it. I couldn’t get in my car and lock the door fast enough. Honestly I don’t know what to make of it, but it’s dreadful.. and I was wondering if anyone else has similar episodes?

Edit: for clarity I am a grown man that isn’t very easily frightened. This isn’t common for me, it’s almost exclusive.
