I sent my self an email

oK, I Know this may sound really weird but about a week ago I dreamt I was over at my friend's house , just chatting, like any other day, but then I realized I was dreaming because I noticed something unusual in the way things were placed around the apartment, so I became lucid and I talked to my friend and told him that I was sleeping, and I don't remember now what he told me, but he came up with the idea of me sending me an email, he said something like "why don't you send your self an email" so i took the computer and logged in, can't really remember what website it was, hotmail, yahoo, facebook? however I just remembered I typed something really longggg explaining I was sleeping, and the colors around, objects, etc. describiing where I was.

So today, just now about 30 minutes ago, I got an email with my name as the sender, and I'm like "no fucking way, imposibble" I was afraid to open it, I was really scared, I felt my heart beating really fast like I was going into shock, I walked around and tried to calm down, I just opened it but all I found was "sfjfjjskdkgh g dhgjksdg sd ghjsdkjgk sdg sdgsdg sd" what has really happened" . I don't think it could posibbly be the email from my dream, cause that's not what I wrote, but also How in the world do I get an email from myself, it's not like someone knows my password or something, I haven't told this dream to anyone either way, so does anybody have a logical explanation for this?!!

I had experiences of me being able to connect to the internet. I think because its like all wifi now and hows that's just like waves of information you brain sometimes tunes in. Hold on I wrote this down Pretty Trippy, "So, I was on my computer in my dream which for me is really commen, anyways I remember going on HF and sending myself a Private message saying don't forget to bring him the money(I browse HF in the morning and I owed this guy money which I forget for a week straight) So I go on HF in the morning remembering the dream and was just like lets see what happens. I opened The PM which freaked me out that I was there and it said, "kkkkkkkkkkkkklllllmmdl". Strange Experience, nobody believed me, before I registered on this site which is why I didn't post it. Pretty intense
