Are there any accounts of lucid dreamers being able to affect waking reality objects from the lucid dream state?
Not unless your sleepwalking.
example please
I haven’t from a dream but back when I was doing astral projection I had an experience of this then.
What happened was my children were in the kitchen getting ready for school and I decided to attempt to astrally project into the room with them to see what they were up to (and I was curious if I did if they would notice me, both my children have some psychic ability).
I thought my attempt had failed so was about to give up but then my kids freaked out and came running into my bedroom and told me a chair had moved, slid across the floor. When I asked them where the chair had been, it turned out the chair wasn’t where it should of been and was actually placed in the very spot I was trying to astrally stand in.
I’ve no idea how it was moved in my attempt but it was interesting. (my children had no idea at all what I was trying to do in the bedroom so didn’t know I was trying to astrally project into that very spot).
