Strain/tingling sensation on temples when in deep meditation- third eye?

Once I’m in my deepest states of meditation I typically really feel a really distinct feeling of tingling and presssure in my temples. The primary time it occurred I hadn’t even heard of third eyes or chakras and it was type of scary so i finished for a couple of seconds, and once I began once more I felt the feeling instantly with out having to deal with my breath/existence for five+ min. Is that this my third eye? why is that this taking place? it’s a tremendous distinct feeling.
