First of all, hi, I am a new member here
Now, I had this experience last night, and it might be even the wrong forum but I didn't find any other place to post this... here we go :

During the past few months I have much personal problems , which I wouldn't like to discuss. At about 23:00 last night after bringing it all again in my mind I had a shock and broke down crying really really bad.
A few hours later I'm off to bed.
Now, I don't remember the dream content but this is what happened :
I remember waking up in the middle of the night laughing out really loud (probably because of the dream's content) and everything seemed ridiculously funny. this continued the whole night.

I'm looking for an explanation about these two extremes. I wasn't expecting to either dream nor having this kind of experience.From Crying to the point of actually being "detached" from the environment , to laughing out while I'm sleeping. One thing to make note however is that I did NOT laugh IN the dream but in reality.

I hope you can make sense out this and give me some information. Thank you.
