Welcome to the forums, Ryan! Glad you decided to join :)
Great job on having three lucids so far! It sounds like zombies/zombie related things are your dream sign! Dream signs can help you become lucid, so it's good you already know what yours is. Read this [IMG]Dream Sign Tutorial[/IMG] for more information.
Good luck trying MILDing! Have you looked at
Naiya's Simple MILD Guide? I definitely recommend reading it if you haven't already. Good luck, and keep it up! If you have any questions just send a PM, and I will reply to it as soon as I can.
