Bisexual?

So I’m a girl, and always been into guys and the thought of myself being gay I just told myself no but lately I’ve been fantasying about what it would be like to kiss a girl.

The other I night dreamt about kissing a girl and I liked it and when I look at girls I’m like Ugh I would kiss her or I would think about her naked or something like that and it’s scary because I don’t know if this is what I want....any advice?
