Recently, I went through my portal to get to the nether, and after it got past the "loading textures" page, it brought up a screenshot, basically, of what it looks like when you first get to the Nether. I could see a little bit of it, but it looked like I was looking through the portal. However, that was all that it showed me. I tried hitting Esc to bring up the pause menu, but the game was just frozen. So I exited out, relaunched Minecraft, then tried opening my single-player world up. This time, after it loaded, it made the sound of a ghast, and it looked like I was inside the ghast. I could see its eyes, and a whole lot of white. But again, it was frozen. I keep trying to open up the world, and it freezes on various other positions. One, it looks like somehow a skeleton went through the portal with me, but it may just be a Zombie Pigman. Sometimes the game just completely crashes, but I'm unable to ever get a crash log for it (I've tried many different methods). I have no idea what's going on, and it's making me sad. I just wanna play my game Please help.
