this behavior *can* indicate neurological problems, particularly if it gets worse as he gets older - or it can just be a kind of super-possessive anxiety that some cats get when they are first bonding with someone, if any little thing goes wrong in the process, or not just exactly like the cat thinks it should go. But only your more excitable cats are prone to this -- for example, this often starts when the cat is cuddling with you, and you get up to go somewhere else, but the cat will "dog" you, and cut in between and in front of your feet, getting bumped in the process -- they immediately think that you bumped them on purpose, and they might start nipping or scratching at your ankles, they wind around your legs even more, getting really distressed and anxious, and you're like: what the heck do I do now?? It can be a little trigger like this that starts them off with the hissing. It's happened three times with cats I had or was fostering; the best advice I had on the problem was to keep resolutely walking, even though this meant you were going to be kicking the kitty as you went, without doubt. Awfully hard, but the only other option if just standing there for the rest of the night. Anyway, I ended up with hissers and they had other problems too indicating insecurity. Your Bengal sounds like this exciteable type. He probably will continue that way, but as long as he doesn't start swiping and scratching at others, that will just be his way.

One thing you want to check is, is your kitty marking his terretory or not. If not, I would suggest, taking a damp hand towel, rub it on his back then on the corners of the place you live. Cats don't care to be moved and freaks them out if their smell is gone. They need the comfortableness of home.

You know, it's something to think about. :)

Good Luck!
