Absolutely. That wouldn’t be the case if the lines carried DC current, but you’re well grounded and human bodies have a small capacitance which can result in what you’re describing. It’s not dangerous but definitely unnerving. AC current flowing in the lines induces current in pretty much anything nearby that is grounded, even in a vacuum.
To AC current, air/vacuum has this property.
