Intelligent Haunting?

My family and I moved into a newly built apartment 6 months ago, But stuff just started happening 3 weeks ago.

First time something happened: I got done watching a movie. It was around 11pm. My kids were asleep in their beds. I had all the lights off and the TV on. Got up and used the bathroom, came back to my front room and the light for my back porch was turned on and the backdoor was unlocked. I NEVER turn that light on because I don't go on the back porch at night.

A few nights later, around 10pm, I took my son into his room. When I walked into his room his toy car came on and the lights and sounds went off. For no reason at all. It has NEW batteries. I made sure it wasn't old batteries. The next night, his other toy car turned on, lights & sounds went off and suddenly cut out. (Remote controlled, and the remote hasn't been seen in quite some time. Months)

Once again, a night later, me and my son walked into his room, and this Rock & Roll Elmo made a sound like a wound up race cars tires being let go. Next to Elmo was a Tonka truck, Buzz Lightyear figurine, and a baseball glove & ball, none of which can make that sound. I played around with Elmo to see if I could repeat the sound I heard. I physically couldn't force it to make that noise again.

Three nights ago, I was walking by my son's room, the door was open but no light was on. I felt like someone was watching me. My son was in my daughter's room watching a movie, so it wasn't him.

My daughter has started to wake up at about 2:30 AM, and talking & giggling. Her room is completely black so it's not like she is talking to a toy because she can not SEE. It's weird. And she started this after 2 months of sleeping the ENTIRE night, without waking up. Maybe that's not a ghost and her just being a silly 4 month old baby. But it creeps me out when I hear it going on.

Now for the part that really scared me. Last night/early this morning (2:30AM). My son ALWAYS wakes up and uses my bedroom's bathroom (he's scared to use the other bathroom without lights on). So, he gets up and when I hear him in there, I get up so I can tuck him back into bed when he is done. I used the bathroom and went back to sleep.

Around 3:30AM I suddenly wake up because I could FEEL, but not physically see, a man walking into my bedroom and walking to my side of the bed, and I felt him watching me for like 5 minutes. I pulled my blanket over my head because I just couldn't take the feeling of it anymore. However, the feeling of it being there hadn't gone away. This wasn't a dream, I was completely woken up when this was going on... I finally fell asleep. My son comes in at around 6AM and crawls into bed with me. He asked me why there was water on my bathroom floor.

I was tired and didn't think anything of what he was asking. As I'm waking up I go into my bathroom and there's a puddle of water. I checked the ceiling for leaks, nothing. Checked the toilet for leaks, nothing. I know it wasn't my son because I asked him if he did it. He is at the age where he tells on himself if he has done something and I ask him about it. And no it wasn't pee. It was water.

I told my honey what happened and what I felt, and he said he woke up around the same time because he felt like someone was near his hand that wasn't covered up.

I am thinking about doing an EVP session tonight. What's your thoughts on what's going on in my home? What should I do?

Also, I'm not scared of this man that was in my room. It was more startling because someone who wasn't invited was there with me. I'm not scared of ghost/spirits/ whatever you want to call them.

PLEASE HELP. I've talked to friends & family and no one seems to believe me.
