Am I going crazy or is this a sickness?

I live alone, a bachelor, and do pretty well for myself. I read that depression and anxiety can do things to you but I am pretty happy. But weird things have been happening.
1. When I'm sitting in my room out of the corner of my eye I see a man walk up and look in from the doorway, but when I look to see there is no one there. It's been about two months now and it's happened like four times in three different rooms.
2. When I get up at night be it to take a leak or get something to drink, naturally it's dark but on two occasions I can feel something there, like an outline, like when someone is trying to sneak up on you but I reached out and nothing but air but I felt something was following me.
3. My den is downstairs and a living room both on opposite sides of the kitchen and dining room, I wanna say three occasions I walked passed the kitchen on my way from the living room to the den or vice versa and clearly saw a small man standing there but when I stop and look back there is nothing there.
4. Lately I've been experiencing that thing where you dream that you trip or fall and your body jumps and it feels like you fell so it wakes you up. It keeps happening almost every night, not so much a problem because I think it's actually pretty cool but still I don't think it should be so constant.

I know my house isn't haunted, it was built in 2002 in North Las Vegas, NV. I've been getting more and more paranoid lately too, I find myself getting home and I check the backyard and the whole house, don't know why just do. Now it's starting to freak me out and possibly starting to affect my social life, a few buddies came over earlier this week, we knocked back a few but I found myself on the verge of asking them to stay the night, I know I'm a grown *** man.
I have no significant problems in my life, my parents are healthy, my brothers are doing good, my nephews are all fine, business is booming, aside from number 4 I have no trouble sleeping, I'm in good health, I can't find any reason. This has never happened before. I figure it's maybe because I'm in a new home but I've been here for about 7 months now and it's been peachy until the last two months.

ok you could be displaying an illness you have managed to ignore. or you could have something else going on. try seeing your doctor if there is no signs of anyone breaking into your home. and there is nothing missing or nothing tampered with. it could be that you are experiencing a type of depression or have an issue that is caused by recent events.

No, I don't think your crazy. In my last home (also in Las Vegas) the up stair master bedroom just had a creepy weird feeling. It was only after we moved out did a friend and I compare notes. She noticed it when she helped us move in and didn't want to scare me.

Your house being built in 2002 doesn't matter. It could still be haunted. There have been hauntings in brand new homes around the Valley. It could be someone who was killed in that location, an ancestor of your who has passed on, or if you have antiques or second hand items spirits could attach to that.

I'm actually reading a book right now about haunting in Las Vegas. It's called Welcome to Haunted Las Vegas Nevada by Tracie Austin-Peters. I got it in the Mob Museum store near Fremont Street. The author is the founder of the LVSSI and has stories about hauntings in unlikely places around Las Vegas. There is additional proof on the LVSSI website (see below).

I know this may sound silly, but try talking to it and seeing what it wants. You can also try cleansing your home with Sage and/or salt.
