Hello and welcome to DreamViews!
So you tried to have an OBE and saw your mom and sister. If you knew you were dreaming and aware, then it was a Lucid Dream. Astral Projection and things like OBE are far more advanced stuff to learn. I mean it might not be hard for some people but it all depends on the individual. An important thing to remember is that to become successful at OBE it is important to master Lucid Dreaming or at least be well at it with a lot of experience. If you are, then go on and try OBE. I haven't had an OBE and not focused on it right now because my focus is on lucid dreaming right now. So I don't really have much advice for you but I would say you should learn more about OBE online and on different sites (this site is great to make thread posts and ask questions). If you are going for OBE and really want to experience it, then don't back out and go for it. Good luck!
