I would advise against an exploratory journey today. My head appears to be filled with a sort of viscous liquid. Visibility would be very poor and I don’t think it would be safe. My head is also experiencing spontaneous and spasmodic explosions that dispels this viscous liquid at great speed.
At other times you’ll need to be well prepared. I’d recommend rope and abseiling equipment. A compass, map and GPS are recommended. My brain appears to contain wormholes that will render the map, compass and GPS pretty useless at times. One moment you’ll be fighting off T-Rex and the next dealing with a multicoloured avalanche. So a spade might be helpful and/or some sort of satellite alert system so people can come and find you. Or just take a tardis! You may want to get out quickly.
Take a psychologist with you to try to help you understand the unfathomable and disjointed places and things you’ll encounter. Perhaps an enigma machine would help? Good boots. You may need to run from things. Shark killing equipment. Desert island survival odds and ends. Definitely take Bear Grylls. He’ll be very useful. Oh and don’t forget your sense of adventure and sense of humour. Watch out for zombies… they seem to appear when the sharks, dinosaurs and avalanches aren’t happening.
Hope this helps! Have fun. I do.
