Nazca Lines, Mystery Booms, Interdimensional UFOs

Some interesting links I've found this week:
• Could Nazca Lines Have Been Made by Astral Projection? – The Nazca geoglyphs have long been considered a puzzle, and the mystery of their creation is debatable, although they were clearly constructed to be seen from the air. Did the makers master the techniques of out-of-body travel?
• Things That Go Bump in the Night – Brad Steiger looks at the phenomenon of mystery explosions that seemingly manifest from nowhere for no reason and startle area residents. He presents records of a rash of unknown things that went "boom" in the night in the 1950s and '60s.
• UFOs and the Interdimensional Hypothesis – Project Delphos Manifesto hopes to promote research aimed at proving that a many UFO sightings are of an interdimensional or paraphysical nature.
