The one con I went to bordered on being entirely too much for me. Too many people hugged me (mine is not a hugging culture). There was so much time spent indoors I had an actual real life panic attack. And afterwards I discovered strangers had taken my photo without my permission. The urge to hide in a hole was great.

On the other side of the coin the intensity of the bonding with the people I am close to a bit overwhelming as well. I wanted to take them home in my pocket.

I don't know that I could ever do it again.

I can certainly see why you'd dream about it.
