I don't mean that they walk IN the house.
After a long strip mining trip (day 18 IIRC, Normal Difficulty), I started building a new house, when suddenly.... 3 Endermen appeared far on the horizon, walking towards me.
It was noon, and it wasn't raining; I thought Endermen would teleport somewhere else because of the sun, but they kept walking/teleporting on my direction as if they were planning to kill me!
They walked past me *phew*, and went on forward until they reached the ocean, then they teleported back near my house (100-50 blocks away).
I'm wondering if this is because the game wants me to go to the End, or perhaps I may be near a dungeon?
I read the wiki, and it does not explain this behavior, and it didn't happen ever before 1.8
