I night ride at least once a week and almost exclusively alone. And, "Yes", I do very-very-very occassionaly get that irrational feeling that makes you pedal extra fast to get away from the spellhound that is not, and never was, there.
In truth you will almost certainly be the most dangerous creature out in the woods at that time of night.
……………….the only real danger is our own stupidity, so take it a little easier and you should be ok.
Badger interfaces are quite common, because they are not the most perceptive or fearful of creatures so they don't bother doing anything to evade you until the last minute. But as long as you are leaving yourself that extra per cent safety margin you should be alright.
It is also makes good sense to restrict night riding to trails you know.
There are some odd things out there at odd times though………..
