Would you go into a portal if one opened in your house?

You are listening to music and all of a sudden the hairs on your body raise up and you hear an electric humming and all of a sudden some portal doorway opens in front of you. You can peer in a bit and see a landscape but can't make much out because of electrical discharges. Would you be up to a new challenge and be willing to walk through it? But make up your mind fast because the image is fluctuating meaning the doorway will close within a few minutes. What would you do?
Go for it or wuss out?
