Update, January/12/2018. According from three players in the comments.. It seems like The First Method or The Second Video doesn't do anything to help.. I remove it to save time.. If the Second Method or The First & Only Video doesn't work or anything. Please do let me know for me to update it as soon as possible when I find a replacement. Thank you and Good Luck on your Gamer Journey!
Update, September/06/2019. It seems like 1 Video even though it did help many people.. It's probably best to put out 2 more videos for Inception Achievement.. Hopefully it allows more people to get this rather annoying achievement.. As usual.. Do your best, Stay calm and Continue your hunt for Achievements!
Original Post, Edited on September/06/2019. As Lightsup55 mentioned. This Achievement could most likely be unlocked in Minecraft Version 1.2.3 or Later.. However.. Even as I closely followed his Guide to the very last step and The achievement never pop up.. I did a bit of research, And according from a information on Youtube... It says something like you got to keep repeating the Process.. Somehow...
I got this achievement as October/19/2017 by following the Guide in this Video.. Here is The Video or URL (Down Below).. In the Video on Youtube, This is the Second Method of The Person who got the achievement and even though (Strangely).. He got it for Minecraft Pocket Edition. The Achievement on Xbox One has either way unlocked successfully with the Guide from Idk Productions on Youtube.. Please have a look.
(Warning: The video could have a Loud Volume.. Recommend to lower your volume in your device just in case.)
Note: The Video on Youtube or by The URL, Isn't really my Video.. It has been made by Idk Productions.
Two more additional videos.. Hopefully they come in handy. Just in case like the first video.. Be sure to lower the volume.
The 2nd Video is made from: therednaz on his channel.
The 3rd video is made from: M&T GAME on his Channel.
All three videos are not my own work.. Well that is all.. Hopefully you all can make the achievement pop as best you can.. Good luck and Do your best to continue your hunt for Achievements!
