We were repositioning our aircraft Part 91 from UDD to the East Coast on an IFR flight plan. We picked up our clearance on the ground and read back the clearance to SOCAL. We read back cleared ... via the UDD obstacle departure PSP-DEJAY... Once airborne we followed that clearance as we thought that is what we were given. As we departed the PSP VOR we were given a terrain warning from SOCAL and given instructions to climb to 13;000 FT and fly a new heading to avoid terrain. Our aircraft never did give us a terrain warning but we were very confused. The issue and concern is we were supposed to be flying to 'DEWAY' Intersection and not 'DEJAY'. I find it very dangerous to have two intersections with very similar sounds and spelling that close together in the same airspace. Having two similar intersections caused us confusion and could of caused us to fly into terrain. We appreciate SOCAL doing their job but would ask that one of those intersections named be changed.
A corporate jet pilot reported that ATC issued a terrain alert along with a heading and altitude change after the flight crew began navigating to DEJAY Intersection in mountainous terrain instead of to DEWAY.
