To do that with a human being, they are either going to have to fly into you or land on you. There are vampire bats and if my memory serves me, they have to land on larger prey to suck but please don't worry, there are none in the US, the nearest are in Mexico as far as I know.
So, its going to be the insect, nectar or fruit ones that could be the one you are thinking of. They really don't want to eat us anyway so I don't think its likely.
You can hear them using eccolocation to navigate and they do call to hunt their prey, or they do in the varieties I know of in the UK, but this is to detect the location of their prey and zoom in on them.
Many varieties have a sort of sucking noise to their eccolocation. If they fly overhead making their calls, you would hear them as they are in our range. Otherwise you would need a bat detector tuned to the frequency of the species and range is limited even then!
Do you think it could be an insect bite? If you live in an area with bats, its could always be an insect and the bats are just around hunting...in which case they are doing you a favour because they will be most likely eating any flying insects for you.
Your last sentence is also a symptom of anxiety. Do you suffer from an anxiety or panic disorder? If so, this is the likely cause.
