Nah.. the only kind of nightmares that I have had is what I truly fear more than anything else in this world.. that's losing my family.. I've had dreams where I've killed off family members, but for self preservation, but can't go back to sleep on those.. They are far and few between thank goodness!
Yeah, those continuation dreams can sometime drain you the next morning. Had this one dream like that, went as far as staying awake for a good 30 minutes and picked up right where I left off in the dream.. they drain me.
I have had plenty of alien dreams lol and none of them cliche.. and out of those many, I have only had one that I questioned, still do to this day. But since I wasn't abducted in it, then I can't scream abduction lol I found my dog outside my room.. with closed doors.. he always slept with me and the rest of the dream was more real like than anything else I have encountered, but since there is no other proof other than the dog.. I just leave it as "anything is possible"
As a child, I trained myself to remember my dreams, down to colors and what flowers sat in a vase.. and for some reason, I can actually read in my dreams.. I found out years later that you're not suppose to be able to read in dreams lol I have also learned how to tell a dream from reality ANYwhom.. I have always enjoyed my xfile dreams for many reasons, relief from reality in a bad time, the wonders of what my mind comes up with and so forth. They never bother me.. and I've had them from eyeballs chasing me to the devil chasing me.. from being on other planets to being in my hometown but more futuristic. I could fill a book!
