You humans seem to be confused on faster than light travel, and have barely even begun to conceptualize traveling beyond the space bounded by light and into other dimensions. I thought I would make this handy tutorial.
Materials used: Giant Sequoia, Samsung Galaxy S8 Smartphone, PhotoShop, Deep Dream Generator.
Step 1: Fully engage your right parahippocampal gyrus and focus your attention on the giant sequoia needles.
Step 2: When you feel a tingling in your basal ganglia, expand your consciousness outward to meld with the tree. Allow your corporeal form to dissolve and cast your brain impulses into the sequoia. You may feel a disorienting sensation of dizziness as you leave our dimension. Make sure your phone is set to "airplane" mode and your seatback trays are stored in the upright position.
Step 3: Explore the alien dimension!
