As a child I think I didn't consider myself a separate entity from other people for a long time, like we were all one big hive mind, as a result of having this really, tangible sensation around familiar things that I presumed everyone had. I believe I might have had a delayed sense of identity as a result, if that is an actual thing, basically nothing that defined a border between me and the next person. I never had any noticeable language/physical delays as far as my parents can recall. Think I was just a strange child, mentally. Around the time of having this energy/smell/taste sensation, I also became very preoccupied with mind-reading and similar things, which in hindsight probably reinforced my own belief in this universal sensation because it spoke, again, of some hidden inter-connectivity between everyone, which is ironic in hindsight.
