A normal phase, or something more?

Elliot has been real clingy lately, most of the time. Sometimes he will be more than happy to sit in his crib, playpen, or in his room and play with his toys, whether or not I or somebody else is there with him. But more times than not he throws a FIT, like his world is completely OVER, if I leave him alone, or if I won't let him play with something or run around! He also hasn't been sleeping well the past few nights. He wakes up almost every 2 hours on the dot, and screams and cries. He hasn't been running a fever, he doesn't have a cold, not hungry, not teething, at least that I can tell. He just doesn't want to be left alone in his room. If I take him back to my room and put him in my bed, he goes right to sleep and sleeps the rest of the night. While, at times this is comforting to have him cuddle with me, I definitely do not want him to start thinking that he'll get his way and get to sleep with me every night. He has also never really had a problem "talking" to people he doesn't really know, or to even be held by them, but lately he mostly just wants to get back to me as soon as he can. Is this all normal, or is there something else going on? I LOVE that my boy loves me, but sometimes I would REALLY like some me time, or to at least get some stuff done other than entertaining him!
