Spirit guide asking me to let them in?

Hi, I protected myself and set an intention to connect with a spirit guide through automatic writing. We talked for a while, they gave me there name and I expressed I would like guidance to work spiritually. (Previously been told by a few mediums that I am a light worker) Then they asked me to let them in. To say their name and let them in. Everything felt good but I felt hesitant about saying this but it might be because I’ve watched too many horror movies! Is letting them in normal? Thanks in advance
