So a couple nights ago I had a really interesting experience. I was chaining lucid dreams using DILD method. I did this approximately 5 times and ended up in the exact same location each time surrounded by the same people each time. They were talking to me but I couldn't hear and my speech was nothing more than a whisper and I could not hear them telepathically either. I kept signaling to them that I couldn't hear. Finally about the 3rd return in I remembered I was wearing ear plugs! I took them out in the dream world and amazingly I could hear. This seems to happen a lot to me where I have problems hearing or seeing especially although usually it's during an OOBE. Normally in a lucid dream I can hear just fine. I don't wear ear plugs to bed all the time but I thought that was pretty bizarre that they would affect my hearing in the dream world as well. Would love to hear your similar experiences.
