What happened to me?

Basically, a while back I had an odd experience and haven't figured out it what it was.

It was during a period that I was depressed over school and other things. During this period I usually had odd nightmares where I try leaving my dream and start moaning and eventually wake up with my siblings hearing me. I know this was from stress, these dreams were common then.

Thankfully my life turned around and I no longer experience depression or other things. However, also during that period I slept one night and woke up past midnight from my sleep. Not sure why but something told me it was 3:00 AM sharp. I felt a presence behind me which made me a little frightened but also secured. I felt that I was fine and had nothing to worry about, I I didn't turn around at all and stayed put. Almost like I couldn't move too. At this moment, I felt a connection to space, not sure how to explain this but I felt something was communicating with my heart. Not my brain, I literally read this communication out my heart.

The best I could explain is as if I was receiving messages from something and i couldn't literally translate it. It was several meanings: I've been seeing, I'm here, I know....

It was like all these meanings at once with something telling me I know and see what you've gone through and I am here. Nothing more than that.

Could anybody tell me what I experienced?
